ABSTRACT – Taxonomic study of the first regional scale collection of deepwater invertebrate megabenthos from Australia’s western continental margin reveals a previously undiscovered high species richness and novelty. Benthic samples were taken systematically at 19 sites from Albany to Barrow Island (~35ºS to 21ºS) on the deep continental shelf (100 m depth) and upper continental slope (400 m). At some sites, additional samples were taken across-shelf at depths of 200 m, 700 m and 1000 m, with a couple as deep as 1200 m and 1500 m. Multibeam (swath) mapping of complex seabed topography enabled targeted collection of the epifauna on hard and soft substrates and targetting of features including submarine canyons. A total of 2001 species including 396 (20%) confirmed new species, 876 (44%) previously described species and 727 (36%) uncertain species were identified within the taxa Porifera (Demospongiae), Cnidaria (Octocorallia, Antipatharia and Scleractinia), Mollusca, Echinodermata, Crustacea (Decapoda), Pycnogonida and Ascidiacea. The high proportion of new and uncertain species stemmed from poor knowledge of entire major groups (e.g. the Demospongiae), and from less well studied deep-sea taxa within otherwise well-known groups (e.g. the Bivalvia). Over half the species (1075) were collected only once. Distributional patterns of taxa show the western margin is an overlap zone of tropical and temperate fauna with a strong Indo-Pacific affinity (42% of described species) but an endemic fauna also exists (17% of described species). This paper provides an annotated checklist of all these identified species, along with live colour images of over half the species. All species can be cross-referenced to images and other collection information via a unique eight-digit computer code maintained in the Codes for Australasian Aquatic Biota database. The research provides valuable information for consideration in the regional marine planning process and all biological specimens are lodged in Australian museums to enable ongoing examination of the diverse and largely undescribed fauna.

McEnnulty, et al. 2 INTRODUCTION SCOPE Knowledge of the benthic invertebrates on the western continental shelf and slope of Australia is limited. Collections by French and English explorers in the 18th and 19th centuries generally were from shallow coastal waters of considerably less than 100 m depth. This first account of composition, geographic range and novelty of deep megabenthic invertebrates from the vast western continental margin of Australia constitutes a significant advance in knowledge for this region. Our data are from the first systematic survey of the deep shelf and slope, and are based on authoritative taxonomic identifications for six dominant taxa of megabethos (i.e. animals large enough to be sorted without microscopy and easily caught in bottom trawls with 25 mm stretched-mesh net cod-ends) from the survey. The information will aid regional marine management planning by providing insights into areas of high species diversity and endemism, and the associations of fauna with their habitats and geological features affecting their distribution. BACKGROUND Deep continental margins, especially the deep continental shelf and continental slope to depths of about 1500 m, are areas of expanding human use for fishing and for mineral, oil and gas extraction, and a priority target for conservation (Williams et al. 2009; Buhl-Mortensen et al. 2010). Knowledge of species distributions, and biogeographical patterns, are fundamental in planning for sustainable use and effective conservation of these often large marine areas. Australia’s current ecosystembased, integrated and regional-scale planning initiatives depend on the identification of natural ‘bioregions’ as planning units. Such ‘bioregions’ initially only incorporated data on the distribution of fishes (Heap et al. 2005; Last et al. 2005) because benthic invertebrate biodiversity was insufficiently known or integrated to be included in the national scale analysis of biological distributions. Accordingly, it was uncertain to what extent the distributions of fishes represented the distributions of the larger benthic invertebrates in this national bioregionalisation. The gaps in knowledge, and the imperative for Australia to implement its national network of marine protected areas by 2012, were primary stimuli for additional surveys of benthic invertebrates in Australian waters. This paper, and a companion analytical paper (Williams et al. 2010), report results from one of those surveys. Research on the benthic invertebrate fauna of continental margins (deep shelf and slope depths >100 m) has been conducted in relatively few areas of the world oceans, including the northeast Atlantic Ocean and Gulf of Mexico (Howell et al. 2002; Macpherson 2002, 2003; Wicksten and Packard 2005; Escobar-Briones et al. 2008; Rowe and Kennicutt 2008; Narayanaswamy et al. 2010); the northern European continental margin (Gray et al. 1997; Gage et al. 2005) and the north-west Atlantic (Georges Bank – Thouzeau et al. 1991); the north-east Pacific (Ruhl 2007) and off New Zealand to 3,000 m depth (Fell 1958; Clark and McKnight 2000). In Australia, information on the slope fauna comes from sporadic collections that have provided numerous specimens catalogued in most Australian and some overseas museums, and has resulted in many taxonomic publications. In southeastern Australia, the diversity of megabenthos has been documented on seamounts (Koslow et al. 2001; O’Hara 2007, 2008a), in submarine canyons (Schlacher et al. 2007) and for the temperate deep shelf (Whitelegge 1900; O’Hara and Poore 2000; Ward et al. 2006; O’Hara 2008b). An extensive survey of macrofauna and larger megabenthos was undertaken off south-eastern Australia by Museum Victoria (Poore et al. 1994). However, few syntheses of distributional patterns have been undertaken of slope invertebrate faunas over wide geographic ranges in Australian waters, and regional studies are lacking. Off south-west and central Western Australia, Williams et al. (2010) presented an analysis of the distribution patterns of the benthic invertebrate communities in relation to broad-scale environmental patterns, but details of the species and their distribution were not included. Such detail is the focus of the present paper. The waters of the western continental margin of Australia contain geographical features such as canyons, seamounts, seeps, the largest western coastal fringing coral reef in the world and the unique southward flowing eastern boundary jet, the Leeuwin Current, from Ningaloo to Cape Leeuwin (22°S to 34°S) (Waite et al. 2007). In the Indo-Australian basin north-west of Australia, shallow, warm, less saline, tropical Indian and West Pacific Ocean waters mix with subtropical Indian Ocean water before joining the Leeuwin current’s southward flow along the shelf break ~250 m (Domingues et al. 2007). Beneath this the more saline, Leeuwin Undercurrent flows northward along the upper continental slope (~250–400 m), sourced from subtropical water Indian Ocean water, South Indian Ocean Central Water, Subantarctic Mode Water and Antarctic Intermediate Water (Ridgeway and Condie 2004; Waite et al. 2007). Lateral exchange with the offshore ocean plays a large role in the coastal boundary system, with the western edge of the DEEPWATER MEGABENTHOS OF SOUTH-WESTERN AUSTRALIA Leeuwin Current and waters east of 100°E subjected to intense eddy activity, the strongest eddy kinetic field in all the eastern boundary currents globally (Domingues et al. 2007; Feng 2010). Once the Leeuwin Current reaches Cape Leeuwin the more dominant destination is offshore advection into the south-east Indian Subtropical Gyre (with the recognised subsequent loss of larvae). The second destination is rounding the south-west corner of Western Australian and combining with the South Indian Ocean Current (35–37°S) to form the boundary jet moving along the southern Australian continental slope and then down the west coast of Tasmania (Domingues et al. 2007). Waters off Western Australia are recognised as globally significant biodiversity hotspots for coral reefs and endemism (Roberts et al. 2002). The north-western continental margin also seems to be characterised by relatively high numbers of species at deep shelf and upper slope depths (e.g. decapods – Ward and Rainer 1988). That the same might be true for the south-west continental slope was suggested for benthic fishes (Williams et al. 2001). The shallow water invertebrate fauna off Western Australia has been studied only in areas adjacent to urban centres and key environmental features – where it is readily accessible. Taxonomic workshops have focused on the flora and fauna of shallow coastal waters at Albany, Rottnest Island, Abrolhos Islands, Dampier and Esperance (Wells et al. 1990, 1991, 1993, 2003, 2005; Wells 1997; Walker and Wells 1999). Shallow water surveys have been undertaken in the north-west, e.g. the Dampier Archipelago (Jones 2004), and the north-west atolls, e.g. Mermaid, Scott and Seringapatam Reefs (Bryce 2009). Various publications on shallow Western Australian invertebrates include: crustaceans (Morgan and Jones 1991; Jones and Morgan 2002), molluscs (Wells and Bryce 1988, 1993; Norman and Reid 2000) and ascidians (Kott 1985, 1990, 1992, 2001, 2005a). Some more general works (Allen and Steene 1994; Edgar 1997; Gowlett-Holmes 2008) include descriptions of some species that extend into deeper waters; nevertheless, the benthic invertebrate fauna of Australia’s western margin is little sampled and poorly known. Australia’s west coast was visited by scientific biological expeditions from as early as Dampier (1703). However, the sampling effort generally focused on land or waters (often considerably) shallower than 100 m, and hence the deep water fauna remained completely unknown. The Baudin expedition (1801–1803) (Péron and de Freycinet 1824) collected in very shallow waters along the coast. Two German expeditions led by Michaelsen and Hartmeyer on the Meteor in 1900 and the Hamburg in 1905 sampled mainly off Shark Bay, 3 but also in south-west Western Australian waters, the relevant taxonomic papers are as follows. The Echinodermata type material from that voyage, described by Koehler (1907), Erwe (1913) and Döderlein, (1914) is lodged at the Western Australian Museum, Perth (WAM). Additional material is described by A.H. Clark (1911) and H.L. Clark (1923). Broch (1910) and Kükenthal (1910) described the Alcyonacea and Pennatulacea. A few of Kükenthal’s 1910 types are lodged in the WAM although most are in the Museum of Natural History, Berlin. The Mollusca were later described by Thiele (1930) and the brachyuran crabs from the Hamburg Museum expedition were described by Balss (1935). The Ascidiacea, described by Hartmeyer and Michaelsen (1928) are lodged in the Hamburg Museum. Some of these voyages also resulted in species descriptions for sponges (Lamarck 1813–1814; Hentschel 1909, 1911; Weltner 1910) and subsequent revisions (Topsent 1930, 1932, 1933). In 1908, dredge samples of molluscs were taken off southern Western Australia and in the Great Australian Bight (Verco and Cotton 1935). In 1910– 1912 the federal Fisheries Investigation Ship (FIS) Endeavour conducted two trawling cruises off the mid-west coast of Western Australia, from which the echinoderms were described by H.L. Clark (1916). Octocorals from Dr E. Mjöberg’s Swedish scientific expeditions to north-western Australia in 1910–1913 are described by Broch (1916) and are lodged in the Swedish Museum of Natural History, Stockholm. The Ascidians from the same voyage were described by Hartmeyer (1919). In 1929 and 1932, the Carnegie Australian Harvard (CAH) Expeditions targeted echinoderms from shallow waters to ~100 m around Australia (H.L. Clark 1938). In the 1960s and 1970s other invertebrate collections were made offshore with the FV Davena, HMAS Diamantina, FRV Umitaka Maru and the MV Sprightly. The HMAS Diamantina sampled the west coast shelf systematically over five cruises from Cape Leeuwin to North West Cape. In 1979 and the 1980s, the RV Soela and more recently the RV Lady Basten sampled on the North West Shelf. Many specimens from these surveys are lodged at the WAM (Echinodermata – Marsh 1976; Marsh et al. 1999; Cnidaria – Griffith and Fromont 1998). The more recent deep-water marine invertebrate surveys have mostly focused on studies contributing to the management of commercial species (rock lobster, crab, prawn and cephalopods) or areas of economic interest subject to exploration and Environmental Impact Studies for developments in the mining or oil and gas industries of the North West Shelf (George 1962, 1966; Ward and Rainer 1988; Wadley and Evans 1992; Smith et al. 2004; Melville-Smith et al. 2006, 2007; Davie et al. 2007). 4 FIGURE 1 F.R.

As wit h material taken elsewhere along Australia’s continental shelf and slope, identifying and resolving the taxonomy of marine species collected from deepwater off Australia’s western margin is difficult in regard to the availability of relevant information about known species. Many type specimens, including the shallow water material collected on historical exploratory voyages to Australia, are lodged in European museums (London, Paris, Hamburg and Amsterdam) rather than in Australia. Although this historic and irreplaceable information has been carefully conserved and the specimens and associated data are readily accessible to scholars, overseas visits add appreciably to the cost of identification (as much of the material is deemed too precious to be loaned). Further, biological collections and associated data, including voucher specimens, and other data from the more recent environmental assessment surveys for industry, may be commercial-in-confidence, not retained and/or not lodged in a museum and thus not readily available for study. STATEMENT OF CONTRIBUTION OF THIS PAPER This paper is an annotated checklist of the megabenthic invertebrate species collected on a systematic regional-scale survey of the deep shelf and upper slope of the western continental margin of Australia, the first of its kind in Australia. Samples were taken from 100 m and 400 m depths at 19 locations from Barrow Island to Albany (~21ºS to 35ºS), and at additional depths (200 m, 700 m and 1000 m) at selected sites. Our checklist provides identifications along with biogeographical information and images of species from six target taxa – Demospongiae: Porifera, Octocorallia: Cnidaria, Mollusca, Echinodermata, Decapoda: Crustacea and Ascidiacea: Tunicata – and for the additional taxa – Scleractinia: Cnidaria and Antipatharia: Cnidaria and Pycnogonida. Many species are new to science or represent new distribution records for Western Australia and Australia. DEEPWATER MEGABENTHOS OF SOUTH-WESTERN AUSTRALIA METHODS SURVEY DESIGN In 2005, benthic marine invertebrates were collected systematically at sites located at one degree longitudinal intervals off Australia’s continental margin between Bald Island and Cape Leeuwin, and one degree latitudinal intervals from Cape Leeuwin to Barrow Island, from the FRV Southern Surveyor (survey SS200510). The sites ranged in latitude from 21ºS to 35ºS and longitude from 112ºE to 118ºE (over 2050 km of coastline). The Perth Canyon site was added into the sampling design as a feature of special interest resulting in 19 sites (Table 1, Figure 1). This sampling approach was designed to position sampling stations within each of the three bigeographical provinces and the two transition zones of the western region designated in the national bioregionalisation by Heap et al. (2005) (boundaries are shown in Figure 1). At each site, sampling stations were targeted at the two major bathomes (depth zones) – the outer continental shelf (samples taken at ~100 m depth) and upper continental slope (samples taken at ~400 m). At selected sites within each province, the sampling design was extended into across-shelf transects to include additional sampling stations within the following bathomes – continental shelf break (at ~200 m), deep upper continental slope (at ~700 m) and mid-continental slope (at ~1000 m). Two very deep sample stations on the mid-continental slope at ~1200 m at Ningaloo and ~1500 m in the Perth Canyon also included (Table 1). Determining the exact locations of the sample sites was supported by detailed maps of the seafloor topography obtained in a prior sister survey of the region by the National Facility Vessel FRV Southern Surveyor in July/August 2005 (SS200507). On that survey, each site was mapped using multibeam acoustics (Kloser et al. 2007) (see mapped examples in Figure 2), the stations surveyed with the towed, high-resolution video and still image system described by Shortis et al. (2008) (see habitat examples in Figure 3). Each station was also sampled with a Smith-McIntyre grab (for sediment analysis and identification of the macrofauna (benthic organisms retained on a 1 mm sieve when elutriated) (lodged with R. Wilson, Museum Victoria). Based on the SS200507 survey acoustic results, geomorphic features – primarily canyons and a seamount, but also other interesting features such as rocky banks and a seep site – were added to the sampling design for this survey as specific targets (Table 1). The multibeam backscatter data from SS200507 allowed specific targeting of separate soft and hard terrains; these stations were nested with bathomes and features if both 7 terrain types were present for the SS200510 survey. Examples of the various habitats sampled are shown in Figure 3 (from the towed, high-resolution video and still image system imagery taken during the mapping survey SS200507). The surveys and associated environmental data are described in more detail in the National Facility survey reports (2005a, 2005b) and by Williams et al. (2010). A total of 172 stations at 19 sites were sampled along 2050 km of the western continental margin between 85 m to 1584 m depths, covering both soft and hard terrains (when present). INVERTEBRATE COLLECTION Megabenthic invertebrates (megabenthos: benthic organisms large enough to be sorted without microscopy and easily caught in bottom trawls with 25 mm stretched-mesh net cod-ends (as opposed to macrofauna: benthic organisms retained on a 0.5–1 mm sieve) were collected with two epibenthic samplers – a ‘Sherman’ sled and a beam-trawl. The Sherman sled (Lewis 1999, 2009) is a robust heavy design for use on rocky (hard) terrains and steep gradients. Its mouth dimensions are 1.2 x 0.6 m. The beam-trawl was a CSIRO modified version of the French IRD design light beam-sled (Forest 1981; Lewis 2010) that was used on soft sediment terrains. Its mouth dimensions are 4.0 x 0.5 m. Images and basic descriptions of both gears can be found at: http://www.cmar.csiro.au/research/ seamounts/epibenthic.htm. Tow distances along the seabed were measured using a USBL beacon attached to the sleds to determine the duration of bottom contact, and dynamic GIS mapping to plot the tow track. Tow direction and duration was dependent on the roughness and topography of the substrate. In general, tows were along depth contours and of about 20 minutes duration (but were less for stations when the sled was full of catch within 5–10 minutes). The entire megabenthic invertebrate catch was sorted and identified at sea by taxonomists to the lowest taxonomic resolution possible; these nominal species are herein known as ‘operational taxonomic units’ (OTUs). Each OTU was counted, weighed (to the nearest gram) and representatives photographed prior to preservation to record live colours, and then included in a continually updated image reference catalogue for comparative purposes while at sea. Proof sheets of images of live specimens are shown in Appendix 2. Specimens were preserved in the standard medium for that phylum (e.g. 70% ethanol – Porifera, Echinodermata, Octocorallia, Scleractinia, Antipatharia, and some Mollusca; 10% formalin – Decapoda, some Mollusca, Ascidiacea and other minor groups).

S p e c i e s t a xo n o my i s t r a c k e d u s i n g a computerised Code for Australasian Aquatic Biota (CAAB). These numbers consist of eight digits and are assigned to each described species in Australian waters. The first two digits define the major group, e.g. phylum; the next three digits define the family or other higher group; the last three digits are the species within that family or group, e.g. CAAB number 28821004 is for decapod crustacean, Ibacus peronii Leach, 1815. A code starting with ‘99’ is an OTU that has not been described or distinguished further. The second two digits in a ‘99’ code are equivalent to the first two digits in a permanent CAAB number; ‘99’ codes are issued sequentially and the order of the remaining digits do not have taxonomic significance. ‘99’ codes are used until a species is described, when it is replaced by a permanent CAAB number. ‘99’ codes can be accessed through the public CAAB database by ticking the project specific codes box on the search screen, e.g. CAAB number 99100454 is for the uncertain sponge species, Clathria (Thalysias) cf. juniperina. Updates to species names can be obtained by checking the CAAB number in the online database at http://www.marine.csiro.au/ caab. The following six major taxonomic groups were selected as target groups for identification to species-level: Porifera (Demospongiae), Cnidaria (Octocorallia), Mollusca, Echinodermata, Decapoda and Ascidiacea (Table 2a). Their selection was based on several factors including their prominence in field collection (80% of catch) and the availability of specialist taxonomists. The remaining nontarget invertebrate taxa were also distributed to museums for lodgement and curation (Table 2b). Identifications have been undertaken on some of these groups i.e. Pycnogonida, Antipatharia and Scleractinia, and these are also included in this manuscript. O nce ident i f icat ion s were completed by the taxonomists, each species was allocated a permanent CAAB number and species recorded in Australian waters for the first time were added to the CAAB database. Published names of new species were upgraded for the associated images. Catch composition records were also upgraded as species taxonomy was reviewed; weights were adjusted for lots where the OTU has been split into multiple species. This checklist uses the following terms to categorise the stat us of species identified. ‘Described species’ are those species whose description was in the published literature prior to this survey e.g. Dermechinus horridus (A. Agassiz, 1879). ‘New species’ are those species 9 collected on this survey determined by the taxonomists to be undescribed e.g. Oparinisis n. sp. A or Ophiura sp. MoV2734 (‘MoV number’ is a unique code used by taxonomists at Museum Victoria). Some new species descriptions have been published subsequent to the survey e.g. Oxypleurodon wilsoni Richer de Forges and Poore, 2008. The remainder of the examined taxa are categorised as ‘uncertain species’. These taxa were identified to the lowest OTU possible (in some cases only to genus or family level) but could not be confidently determined as previously described taxa, or recognised as new species either. The possibility exists that these species may belong to known species but taxonomic uncertainty precludes a definite identification. In addition, some species were identified as uncertain using the ‘cf.’ or ‘?’ prefix. Examples of uncertain species include: Raspailia (Raspaxilla) sp. SS1, ?Hyotissa sp. 1, Bathycrinidae sp. 1, cf.

Unsuccessful (aborted) sampling events and specimen lots with incomplete location data have been removed from the summary analyses. Information on the biogeographical distributions of the previously described species and whether they were new records for Australian or Western Australian waters, or Australian endemics was collated from the literature and the taxonomists’ knowledge. The checklist (Appendix 1) summarises the geographical and depth ranges for each species or OTU recorded on the survey. The data have not been corrected for varying sampling intensity among sites. This list, and all summaries and analyses presented here, represent the upgrades and species descriptions as of December 2010. The checklist (Appendix 1) summarises the geographical and depth ranges for each species or OTU identified on the survey. The species names and OTU designations in this list, and presented in the summaries within this publication, reflect the taxonomic work published and/or received by CSIRO as of December 2010. RESULTS OVERVIEW OF FAUNAL COMPOSITION Porifera dominated the collection by biomass, comprising 86% of the total catch (wet weight). The other target groups in decreasing order, each at least an order of magnitude less by weight, were: Echinodermata, Decapoda, Mollusca, Cnidaria (Octocorals, Antipatharia and Scleractinia) and EDs PLEASE ADVISE F.R. McEnnulty, et al. 10 Ascidiacea. The largest specimen, belonging to the Demospongiae, was a single individual of Biemna sp. SS2 that weighed 37 kg. Additional large individuals in this genus weighed 17, 6 and 5 kg (see Appendix 2: image 10084810). Another 126 individual Demospongiae specimens were over 1 kg wet weight. The heaviest non-sponge invertebrate specimens were of the Holothuroidea and Echinoidea and these weighed less than 1 kg. At sea, the sorting of the samples yielded 1,750 nominal ‘species’ (OTUs) across all the invertebrate taxa (see Table 2a, b), with the six major taxonomic groups accounting for 80% of these. Over 19,000 specimens comprising 2,001 species were subsequently identified in the laboratory by the taxonomists from the six major groups (a further 38 OTUs were only identified at higher taxonomic levels).

(44%) were identified as previously described species and 396 (20%) were determined to be new species. The remaining 727 species (36%) remain of uncertain identity. To date, 42 new species have been described from this collection. Some groups are better studied than others: 89% of the Echinoidea and 79% of the Scleractinia could be identified as described species, while only 5% of the demosponges and 22% of the Alcyonacea were recognised as described species (Table 3, Figure 4c). Of the six major groups, the most speciose was the Decapoda with 521 species. The Mollusca with 481 species (excluding the Opisthobranchia and Polyplacophora) were the second most diverse group, followed by the Demospongiae (372), the Echinodermata (350), the Cnidaria (Octocorallia, Antipatharia and Scleractinia) (180) and the Ascidiacea (77). In addition, 17 species of Pycnogonida and 3 Thaliacea were recorded. Numerically the Echinodermata (6,829 specimens) and the Decapoda (6,206) dominated the collection, followed by the Mollusca (2,588) – excluding the EDs PLEASE ADVISE DEEPWATER MEGABENTHOS OF SOUTH-WESTERN AUSTRALIA Opisthobranchia and Polyplacophora, the Cnidaria (Octocorallia, Antipatharia and Scleractinia) (1,916), the Demospongiae (1,288) and the Ascidiacea (458) (Table 3). FAUNAL DISTRIBUTIONS One-quarter (522) of all the species collected on the survey are new records for Australian waters. Of these, 129 records are the first record in Australian waters for a species previously described from elsewhere in the world; the remaining records are confirmed as new species. Over one-third (726) of all the species collected are new records for Western Australian waters, of these 308 are species known from elsewhere in the world (including the range extension of 175 Australian endemic species into Western Australia) and the remainder are confirmed as new species (Table 4). BIOGEOGRAPHY OF DESCRIBED SPECIES For the 876 species previously described in the literature (and hence with known distributions) collected on this survey, the largest proportion (61%) had an Indo-West-Pacific biogeographic distribution, while only 4% were restricted to the Indian Ocean. Australian endemics accounted for 25% of species distributions, including 5% endemic to Western Australian waters. Southern Ocean or sub-Antarctic species represented 5%, species previously recorded only from the Atlantic Ocean 1%; and cosmopolitan species 4% of the biogeographic distributions. The biogeographic affinities of the identified megabenthos are shown in Table 4 along with the overall species totals for the taxonomic groups. Depth appeared to strongly influence species diversity with many more species collected on the shallower outer shelf (100 m depth) than on the upper slope (400 m) where sampling coverage and intensities were similar (41 compared with 39 sample collections) (Figure 4a). The proportions of the six major megabenthic invertebrate taxa caught at each site are shown for each of the five depth zones (Figure 5). The Demospongiae and the Ascidiacea were collected mostly from the shallow 100 m and 200 m stations and were considerably more diverse (with more species) in the temperate sites south of Two Rocks (Figure 5a,b). These shallower temperate sites appeared to contain abundant hard substrate that provided suitable habitat and access to favourable nutrient flow in the currents for these fixed sessile filter feeding taxa (also see Kott 2008; Williams et al. 2010). Corals were not diverse but were found to be locally abundant. No clear depth or site related patterns were discernible for the Mollusca, Decapoda or 17 Echinodermata at this high level of taxonomic resolution. Overall, more species were collected where sampling effort was greatest – especially in the focus areas of Ningaloo, Albany and Bald Island, and lowest at sites where few collections were made (e.g. only two sample collections at Point D’Entrecasteaux and Lancelin) (Figure 4b). While unequal sample numbers made it difficult to compare site-level diversity across the entire data set, it is interesting to note that the total number of species collected was relatively consistent across all sites for which there were between two and six sampling stations with only Kalbarri (five stations) standing out as richer (Figure 4b). The percentage of described species compared with the uncertain and new species per site was greater for sites north of Shark Bay; accounting for at least 55% of the species (Figure 4b). For sites south of Shark Bay the opposite was found, driven by the large number of uncertain and new demosponge species recorded from the southernmost temperate sites at 100 m depth (Figures 4c, 5a,b). The percentage of described species at each site ranged from 34–63%, lowest at Perth Canyon and highest at Lancelin. The percentage of new species per site was fairly steady between 11–24%, being lowest at Lancelin and highest at Abrolhos. Only two stations were sampled at the Lancelin site at 100 m and 400 m depths due to the narrowness of the shelf and lack of variation in the terrain (steep gradient, compressed habitat, soft substrate – no sponges were collected from these sites). The percentage of uncertain species per site ranged from 19–31%, being lowest at Carnarvon and adjacent tropical sites and highest at Point D’Entrecasteaux. The collection is dominated by a high percentage (>50%) of singletons (occurring at one site only) (Figure 6a) and this pattern is consistent between the six major taxa (Figure 6b). For the six major taxa sampled, 1,075 of the 2,001 species were recorded at only one of the 172 stations sampled. The most frequently recorded species of the entire survey, the hermit crab Paguristes aciculus, occurred at 27 stations from Bald Island to Ningaloo in depths from 100–550 m.

PORIFERA: DEMOSPONGIAE (CAAB NUMBERS 1000#### & 99100###) A) NUMERICAL SUMMARY The Class Demospongiae dominated the Porifera collected numerically with 1,312 specimens; 372 species were identified from 110 genera, 51 families and 12 orders, two additional OTUs were only identified to a higher taxonomic level. A further 21 and 30 specimens not identified to species level were from the sponge Classes Hexactinellida and Calcarea, respectively. A conservative estimate of the number of Demospongiae species new to science resulting from this study is 106 species (28%), 246 species remain uncertain (67%) and only 19 species (5%) were determined to be described species (Table 3). Due to the large volume of the sponge collection, very small individuals and/or fragments <5 g in wet weight were not identified due to time constraints, but these specimens have been kept for future taxonomic study. Of the 372 Demospongiae species recorded, 185 occurred at one station only, while the two most common – Sarcotragus sp. WAM Ng1 (99100345) and Luffariella sp. WAM SS1 (99100343) (Order Dictyoceratida) occurred at 10 sampling stations. Agelas sp. WAM SS1 (99100448) (Order Agelasida) and Geodia sp. NG1 (99100423) (Order Astrophorida) occurred at nine sampling stations (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES Since 67% of the demosponges are uncertain species and 28% are new species, the following biogeographical summary applies to the 5% (19 species) identified as previously described species (Table 4). Seven (37%) are Australian endemics of which five (26%) are Western Australian endemics. Of the remainder, six (32%) have an Indo-West Pacific affinity, one (5%) an Indian Ocean affinity and five (26%) a Southern Ocean or sub-Antarctic origin. At least 106 are new species records for Australia and 109 are new records for Western Australia, this includes range extensions of three Australian endemic species (Table 4). F.R. McEnnulty, et al. It was beyond the scope of this study to research the historical literature and to undertake major redescriptions of the Demospongiae species, some of which may have been found in this study. However, digitised species identification sheets (mudmaps) were compiled for each of the 372 species (see example: Fromont and Gomez 2007; Axinella sp. SS1 in Appendix 3. These mudmaps of Australian sponge OTUs are a standardised format for capturing the characteristics of each designated sponge OTU. They are used by taxonomic experts throughout Australia and thus allow an overall assessment of the biogeography of the sponge fauna, even though many of the species still need to be formally described and named. The synthesised OTUs will form the basis for new species descriptions. The order Poecilosclerida is known to be the most speciose of the all the Demospongiae (Hooper and van Soest 2002). The Poecilosclerida had the highest numbers of species (25%) followed by the Dictyoceratida (fibre sponges), Haplosclerida, Astrophorida and Halichondrida (18%, 17%, 13% and 11%, respectively). Two comparable Australian deepwater projects, one in the Great Australian Bight (GAB) and the other in the Tasmanian seamounts also found Poecilosclerida dominated (30% and 37%, respectively) but the order of dominance of the other orders differed. In the GAB the Halichondrida and Haplosclerida, Dictyoceratida, Hadromerida and Astrophorida represented 19%, 19%, 14%, 11% and 4% of species, respectively (Sorokin et al. 2007), and in the southern Tasmanian seamounts, Dictyoceratida, Hadromerida, Haplosclerida, Halichondrida and Astrophorida represented 15%, 14%, 12%, 10% and 9% of species, respectively (Schlacher-Hoenliger 2007). This western continental margin study differs from the GAB and Tasmanian studies in recording sponges from the orders Agelasida, and the family Plakinidae. In addition, no species of the Order Verongida were found in the GAB and only one species was reported in the Tasmanian seamounts compared to eight species in the present study. This study included tropical locations and surveyed a larger area and a much greater latitudinal gradient compared with both the GAB and Tasmanian studies. This is the first collection of sponges from depths greater than 100 m off the south-west coast of Australia. Recent shallow water collections in the region (Fromont et al. 2006; Fromont and Vanderklift 2009) have indicated a speciose shallow water fauna, and Hooper and Levi (1994) have suggested pockets of apparent endemism occur along the western continental margin of Australia. EDs PLEASE ADVISE DEEPWATER MEGABENTHOS OF SOUTH-WESTERN AUSTRALIA 2. CNIDARIA Only the subclass Octocorallia (Alcyonacea and Pennatulacea) was targeted for identification. However, specimens from the other coral taxa (Antipatharia and Scleractinia) were also identified and are discussed here. 2.1. CNIDARIA: ALCYONACEA AND PENNATULACEA (CAAB NUMBERS 1117####, 99110### AND 112#####, 99110###, RESPECTIVELY) A) NUMERICAL SUMMARY 19 and shows links to southern and northern Atlantic regions. It also provides more evidence for links with the Indonesian and northern Pacific (Japanese) fauna as well as containing some deep-water cosmopolitan species. Since 68% of the Alcyonacea are uncertain species and 10% are new species, the following biogeographical summary applies to the 22% (28 species) identified as previously described species (Table 4). Thirteen (50%) are Australian endemics of which four (15%) are Western Australian endemics. Of the remainder, 12 (46%) have an Indo-West Pacific affinity (46%) and a single species (4%) has an Indian Ocean only origin. Since 38% of the Pennatulacea are uncertain species and 25% are new species, the following biogeographical summary applies to the 38% (three species) identified as previously described species (Table 4). These species all have an Indo-West Pacific affinity with Umbellula huxleyi, additionally recorded from the north-east Atlantic (as well as the north-west Pacific). Over 440 specimens within the Alcyonacea (soft corals, sea fans and sea whips) were identified from this survey. These comprised 117 species, 58 genera and 16 families. Of these, 26 species could be identified as described species, 12 recognised as new species and four as new genera (but as yet undescribed) and 79 species remain uncertain (Table 3). A further 10 OTUs were only identified at a higher taxonomic level and are not included in the following summary. The alcyonacean material was diverse, although the biomass was low for all but a few of the endemic species. I n addit ion, 29 speci men s of t he Order Pennatulacea (sea pens) were collected, including eight species, six genera and five families. Of these three could be identified as described species, two recognised as new and three remain uncertain (Table 3). A single OTU was too damaged to be identified to species level. As in many other faunal groups, identifications are hindered by poor and inaccurate literature in a field where most genera need total revision using modern techniques. Given that there are virtually no comparative records of Octocorallia from the regions sampled, much of the material can be considered as new records. Of the 117 Alcyonacea and 9 Pennatulacea species recorded, 80 and 6 species, respectively, occurred at one station only. The most common Alcyonacea species, Mopsea encrinula (11188009) occurred at six stations at 100 m depths from Bald Island to Shark Bay. The most common Pennatulacea occurred at three stations, Umbellula huxleyi (11216003) was found at 1,000 m from Two Rocks to Abrolhos and Pteroeides sp. F (99110351) at 100 m at Ningaloo (Appendices 1, 2). Only 12 specimens of Antipatharia were examined from this survey; these comprised eight species, five genera and two families, but other material remains to be examined (Table 3). Two described species were identified and six species remain uncertain and no new species were determined. Of the Antipatharia collected, six species occurred at one station only, while the most common, Stichopathes sp. A (99110615), occurred at three stations (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES T h i s mater ia l i ncluded some su r pr i si ng specimens; the biogeographic relationships of some of the species show unusual affinities and the data includes many new records for Australian waters. The data includes specimens previously known from both temperate and tropical regions Due to the low number of species examined the biogeographical summary of the antipatharian data reveals one species is an Australian endemic but not a Western Australian endemic (Table 4). The other described species has an Indo-West Pacific affinity. Myriopathes myriophylla (11158002), For the alcyonaceans, 25 are new records for Australia (six are described species), 27 are new records for Western Australia, three of which are range extensions of Australian endemics. Oparinisis parkeri and O. viking were previously recorded from South Australia and Pseudoplumarella filicoides (1197015) was previously recorded in New South Wales only. For the pennatulaceans, two are new records for both Western Australia and Australia: Scytalium sarsii (11224001) and Umbellula huxleyi (11216003) (Appendices 1, 2). 2.3. CNIDARIA: ANTIPATHARIA (CAAB NUMBERS 1115#### AND 99110###) A) NUMERICAL SUMMARY 20 known from adjacent Indonesia is recorded for the first time in Australia from northern Ningaloo (Appendices 1, 2). Preliminary determinations of the antipatharians from this cruise identified several species that are probably new records for Australian waters; however comparative material is required from the British Museum of Natural History for final identifications. Cupressopathes albies has a West Pacific distribution and the specimen Cupressopathes cf. albies examined from Point Cloates is possibly a new species. Stichopathes sp. A (recorded from Shark Bay and northern Ningaloo) may be Stichopathes cf. ceylonensis from the Indian Ocean. All the black corals examined were collected from 100 m depth except for the endemic species, Parantipathes helicostricha (11161002), which was collected at 1,000 m off Albany (Appendices 1, 2). This species is previously known from deep water from the Great Australian Bight and southern Tasmania as well as New Zealand. 2.4. CNIDARIA: AZOOXANTHELLATE SCLERACTINIA (CAAB NUMBERS 113##### AND 99110###) A) NUMERICAL SUMMARY Prior to this survey, 116 species of azooxanthellate Scleractinia were known from western and southern Australian (Rehberg 1892; Folkeson 1919; Hoffmeister 1933; Veron 1986; Cairns and Parker 1992; Cairns 1995; Cairns and Zibrowius 1997; Cairns 1998; Cairns 2004), representing 16.5% all known species. Of these, 55 species are restricted to waters deeper than 200 m, and an additional six occur both shallower and deeper than the 200 m isobath. The vast majority were recorded from the tropical region (north of Houtman Abrolhos), including nine endemic species (Cairns 1998). Another 18 species are restricted to waters south of Houtman Abrolhos, and only eight are reported from both regions (Cairns 2004). This survey collected the majority of species previously recorded f rom deeper Wester n Australian waters. The azooxanthellate Scleractinia collected included over 1,400 specimens from 47 species, 19 genera and eight families. Of these, 37 species could be identified as described species, three recognised as new species and seven species remain uncertain (Table 3). Of the 47 Scleractinia species recorded, 20 occurred at one station only, while the most common, Stephanocyathus (Acinocyathus) spiniger (11314019) occurred at seven stations at 350–500 m depth from Bald Island to Shark Bay (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES F.R. McEnnulty, et al. Only 6% of the Scleractinia are uncertain species and 6% are new species, so the following biogeographical summary applies to the 79% (37 species) identified as previously described species (Table 4). Five species (14%) are Australian endemics but none are Western Australian endemics. The vast majority, 28 species (76%) have an IndoWest Pacific affinity, three (8%) are considered cosmopolitan and a single species (3%) is known from the Atlantic Ocean only. Eight species are new records for Australian waters and 14 new for Western Australia, while two are range extensions of Australian endemics (Table 4). Dasmosmilia lymani, Phyllangia cf. papuensis, Trochocyathus cooperi, Notocyathus conicus and Truncatoflabellum candeanum are examples of species reported for the first time from Australian waters. Biogeograph ically, the Anthem iphylliidae (Anthemiphyllia dentata and A. n. sp.) were collected in south-western Australian waters. All Caryophyllia species, except C. planilamellata (new record to Western Australia) and C. diomedeae, were collected in the tropical region of the western margin, with the deepest record for the genus being represented by C. scobinosa (new record to Western Australia) from 983–1,010 m depth. C. unicristata, another tropical species, was the most abundant species (see Kitahara et al. 2010). The distribution of Deltocyathus magnificus is extended to southern Western Australia and D. rotulus is reported for the first time in Western Australia. Within the Dendrophylliidae, the most common genus was Balanophyllia with six species, including two new records to Western Australian waters: B. cf. dentata and B. desmophyllioides. The description of one new species of Balanophyllia from this survey is being prepared by Kitahara and colleagues at Museum of Tropical Queensland (pers. comm.). Historically, the colonial corals Solenosmilia variabilis and to a lesser degree Madrepora oculata appear to be the most important deep-sea reef builders in Western Australia (Kitahara, pers. comm.). Solenosmilia variabilis appears to be an important substrate for the solitary species Caryophyllia diomedeae (Kitahara et al. 2010). Although no live Solenosmilia was collected during this survey, live coral was viewed on video footage taken on the survey SS200507. The live Solenosmilia observed was very patchy and most of the reef formations consisted of long dead, possibly subfossil, coral matrix. Many images of the deep-sea scleractinian species from this survey included in Appendix 2 are the first ever taken of freshly collected specimens (examples include Anthemiphyllia n. sp. A (99110618); A. dentata (11304001); Fungiacyathus f ragilis (11301001); Letepsammia formosissima (10299002); Caryophyllia planilamellata (11314042); EDs PLEASE ADVISE DEEPWATER MEGABENTHOS OF SOUTH-WESTERN AUSTRALIA Deltocyathus suluensis (11314021); Stephanocyathus spiniger (11314019); Flabellum tuthilli (11328010) and Truncatoflabellum macroeschara (11328015). 3. MOLLUSCA Over 767 hard-shelled Mollusca species were identified. Of these, 425 species were live-taken and 342 represented only by dead-taken shells. Species from 109 families from the classes Gastropoda, Bivalvia, Scaphopoda and Polyplacophora have been identified to date. Many specimens from this survey cannot be identified to species level at present. In some cases, specimens are recognised as belonging, or thought to belong, to undescribed species. In other cases, the lack of comparative material does not allow a definite identification to be made – this is not surprising as the molluscan fauna of Australia’s western continental margin has been rarely accessed. In addition, many families of molluscs, particularly bivalves and especially those of the Indian Ocean are in urgent need of revision (some most-recently revised in the second half of the 19th century). Some groups, particularly those of interest to the shell-collecting fraternity, are reasonably well known and have enabled recognition of new and undescribed species previously not recorded in the Western Australian or Australian fauna, and records indicating an extension of the known latitudinal or longitudinal range of a species. Dead-taken, as well as live-taken, Mollusca specimens were deliberately collected during the second half of the SS102005 survey, examined and lodged at the Western Australian Museum but their identifications are not included in the numerical summaries of this paper. However an example is given for the bivalves to illustrate the usefulness of such collections. The distinguishing of recentlydead from long-dead (or even sub-fossil) material can assist in forming a much more detailed record of a species distribution. During this survey, many species were either rarely or never collected as live specimens, even though their known geographic range was within the survey area. When the few instances in which dead-taken specimens have been included in the data set, they have reinforced or even extended the known geographic and depth distributional ranges. 3.1. MOLLUSCA: BIVALVIA (CAAB NUMBERS 232##### AND 99230###) A) NUMERICAL SUMMARY Over 700 specimens of the Bivalvia, identified as belonging to at least 162 species from 83 genera, 39 families and 10 orders, were collected. Of these, 21 only 62 species could be identified as described species and 101 remain uncertain, reflecting the lack of knowledge on this deep-sea fauna (Table 3). Of the 162 Bivalvia recorded, 100 species occurred at one station only, while the most common species, Venericardia rosulenta (23325016), occurred at 10 stations from Bald Island to Ningaloo in 100–200 m depths (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES No new species were identified and 68% of the bivalves were uncertain species and, so the following biogeographical summary applies to the 32% (62 species) identified as previously described species (Table 4). Twenty-nine species (47%) are Australian endemics but only two (3%) are Western Australian endemics. Of the non-native species, 32 (52%) have an Indo-West Pacific affinity, and a single species (3%) is known from the Indian Ocean only. One previously described species, Amygdalum watsoni (23220073), is a new record for Australian waters and 15 are new for Western Australia, two of which are range extensions of Australian endemics (Table 4). Of interest were the dead-taken shells of Foramelina ?exempla, collected at just one station off Point Cloates in 400 m depth. Foramelina exempla is the only living species of an otherwise extinct family and was previously known only off south-eastern Australia. The Western Australian specimens were all dead-taken, but not fossil shells, and show some differences to the south-eastern species. Further study is required to determine whether they may represent a new species. 3.2. MOLLUSCA: CEPHALOPODA (CAAB NUMBERS 236##### AND 99230###) A) NUMERICAL SUMMARY More than 120 specimens of the Cephalopoda were identified as belonging to 29 species from 21 genera, 12 families and four orders. Of these, only 13 could be identified as described species and 16 remain uncertain species (Table 3). Not all the specimens could be identified due to considerable damage to the soft tissues with 11 OTUs identified as higher level taxa, and no new species were discovered. The majority of specimens were collected by beam trawl over soft sediments with 42 lots collected at 400 m, six at 200 m and 12 at 100 m depths, with only nine lots collected at 700 m or deeper. Not all cephalopods collected were benthic species, with some pelagic species inadvertently caught in the dredges in transit to and from the benthos; these species are thus under- F.R. McEnnulty, et al. 22 represented in the areas surveyed but are included for information. Of the 40 Cephalopoda species recorded, 23 occurred at one station only, while the most common occurring at five stations each were indeterminate Sepia sp. (23607901) and Heteroteuthis spp. (23609902) (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES Since 55% of the Cephalopoda are uncertain species, the following biogeographical summary applies to the 45% (13 species) identified as previously described species (Table 4). Six species (46%) are Australian endemics but none are Western Australian endemic species. Of the remainder 4 (31%) have an Indo-West Pacific affinity and 3 (23%) are cosmopolitan species. No new species were recorded for Australia. Ten Octopodidae species were collected, of which only one, Eledone palari, was previously described. One unidentifiable species of the meso- to bathy- pelagic Bolitaenidae was recorded from northern Ningaloo at a depth of 1,200 m. One unnamed species of Benthoctopus from the deepwater subfamily Bathypolypodinae was recorded from northern Ningaloo waters in the relatively shallow depth of 400 m. Included in the seven species of Sepiidae was the northern Australian endemic species, Sepia opipara (23607006). This species was found at Bald Island in the south-west, considerably extending its known distribution south of Fremantle. With the exception of one unidentifiable Sepiadarium species from deepwater near Bald Island in 1,000 m depth, the three remaining species of benthic Sepiadariidae were collected from 100 m or 400 m depths in both tropical and temperate waters. Sepioloidea lineolata (23608001), a southern Australian temperate species, was collected from Zuytdorp in 100 m, just within its known geographical range, although it is generally found in shallower water to depths of only 20 m (Norman and Reid 2000). At least nine species of Sepiolidae were collected. Euprymna tasmanica (23609001), known from southern Australia, was collected at two northern sites – Point Cloates and northern Ningaloo – in 400 m and 100 m, respectively (it is known to at least 80 m; Norman and Reid 2000). Many specimens of the pelagic or benthopelagic genus Heteroteuthis from depths of 400–1,000 m in the south-west were unfortunately unidentifiable. Of the seven squid species collected, only four are described species. Enoploteuthidae undergo extensive daily vertical migrations and unidentified specimens of this family were collected at 400 m. One unidentifiable species of Chiroteuthis, from the gelatinous, slow moving, deep-sea family Chiroteuthidae, was collected in 1,000 m off the Houtman Abrolhos. 3.3. MOLLUSCA: GASTROPODA (CAAB NUMBERS 24###### AND 99240###) A) NUMERICAL SUMMARY More than 1,600 specimens of Gastropoda were identified as belonging to 267 species from 142 genera, 53 families and seven orders. Currently 85 described species have been identified, six new species (as yet undescribed) were distinguished and 176 remain uncertain species, reflecting the lack of knowledge on this deep-sea fauna (Table 3). Of the 267 Gastropoda species recorded, 187 occurred at one station only, while the most common, Comitas cf. galatheae (99240266), occurred at nine stations from Point Hillier to Barrow Island (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES Since 66% of the Gastropoda are uncertain species and 2% are new species, the following biogeographical summary applies to the 32% (85 species) identified as previously described species (Table 4). Thirty-five (41%) are Australian endemics and of these 12 (14%) are Western Australian endemics. The majority of the species, 47 (55%) have an IndoWest Pacific affinity with the remainder of Southern Ocean or sub-Antarctic (1%) origin or cosmopolitan (1%). At least one species is a new record for Australian waters and seven species are new records for Western Australia. Particularly interesting records for Australia include: Manaria kuroharai (24202215 – no image), previously known only from the Sea of Japan, and Akibumia orientalis (24173001 – no image), collected from ‘soft’ substrate off Houtman Abrolhos in 400 m depth. The only previous Australian record of A. orientalis is a single specimen taken in >1,000 m depth off Sydney in New South Wales. Not all the Opisthobranchia have been identified; to date 25 species have been recognised of which only one, the temperate Australian endemic Tylodina corticalis (24391001), has been identified as a previously known species. 3.4. MOLLUSCA: SCAPHOPODA (CAAB NUMBERS 235##### AND 99230###) A) NUMERICAL SUMMARY The 130 specimens of the Scaphopoda were identified as belonging to 23 species from seven genera, five families and two orders (Table 3). Only three have been recognised as described species, the other 20 are uncertain species, reflecting the EDs PLEASE ADVISE DEEPWATER MEGABENTHOS OF SOUTH-WESTERN AUSTRALIA lack of knowledge on the deep-water species of this group of molluscs. Of the 23 species of Scaphopoda recorded, 14 occurred at one station only, while the most common, Fissidentalium cf. shirleyae (99230208), occurred at six stations from Lancelin to Ningaloo (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES Of the three (13%) described species identified, one is a widespread southern temperate species and the other two are endemic Australian species (Table 4). One of these species, Dentalium potteri, was previously thought to be endemic to waters off eastern Australia and is a new record for Western Australia. 3.5. OTHER MOLLUSCA (NOT EXAMINED) Of the other Mollusca, at least six species of the Polyplacophora remain unidentified and one lot of the Aplacophora remains unexamined. A small amount of additional live-taken material remains unidentified but is lodged at the WAM awaiting further work. 4. ECHINODERMATA 4.1. ECHINODERMATA: ASTEROIDEA (CAAB NUMBERS 251##### AND 99250###) A) NUMERICAL SUMMARY The lack of knowledge of the taxonomy of the deep-water fauna of the western continental margin of Australian is reflected in the Asteroidea identifications. Of the (at least) 500 specimens from 87 species collected in 58 genera, 18 families and five orders, only 28 could be identified as described species (Table 3). An additional six OTUs could only be identified to higher taxa. Twenty-four new species are recorded while 35 remain uncertain. Some are tentatively identified or identified to genus only and probably include many more undescribed species. A new species in the Asterinidae, Aquilonastra shirleyae O’Loughlin, 2009, has already been described from 100 m at Point Cloates and Red Bluff (see Appendix 2: image 25140802). Many of the other new species are likely to remain undescribed for some time to come. Of the 87 Asteroidea species recorded, 54 occurred at one station only, while the most common species, occurring at six stations were Sclerasterias sp. 1 (99250364), Diplopteraster sp. 1 (99250292) and Hoplaster sp. 1 (99250343) (Appendices 1, 2). 23 B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES Since 40% of the Asteroidea are uncertain species and 28% are new species, the following biogeographical summary applies to the 32% (28 species) Six (21%) are Australian endemics, and only one (7%) is a Western Australian endemic species. The vast majority 21 species (71%) have an Indo-West Pacific affinity. One species (7%) has a Southern Ocean or sub-Antarctic origin and another species has only previously been recorded from the Atlantic Ocean (Table 4). Three of the described species are new records for Australian while five are new records for Western Australia, two of which are range extensions of Australian endemics. Eleven genera and six families (Odontasteridae, Labidiasteridae, Radiasteridae, Solasteridae, Porcellanasteridae and Ctenodiscidae) are newly recorded from Western Australia (the latter two families have previously been found off north-western Australia but the records are unpublished). The Radiasteridae, Pterasteridae and Solasteridae are recognised as predominantly temperate cold water families, but were also collected in the cooler deep water in tropical areas on this survey. Of the 28 identified species, all but three are shelf species: Sidonaster vaneyi is known from the Indian Ocean and the Philippines, Ctenodiscus orientalis (see Appendix 2: image 25114001) is known from the Philippines, Indonesia and Tasmania, and Cnemidaster wyvillii known from the Philippines to the Arafura Sea. The affinities of the shelf species are predominantly with the tropical fauna to the north. There are close affinities with the asteroids of the Philippines (Fisher 1919) and Indonesia at the generic level and also with New Zealand (Clark and McKnight 2000, 2001; McKnight 2006). Asterodiscides macroplax (see Appendix 2: image 25128004) was collected in 100 m off Carnarvon; this species is endemic to north-west Western Australia. Specimens lodged at the WAM have been collected from 30–40 m depth at the Houtman Abrolhos by museum staff and from trawls at 60–80 m depth off the Montebello Islands in 1979 on RV Soela (Marsh et al. 1999). Heteronardoa diamantinae (see Appendix 2: image 25125023), collected on this survey from a singe station in 100 m by beam trawl off Point Cloates, was described from a specimen from the 1964 HMAS Diamantina survey collected by beam trawl in 128 m off Point Cloates (Rowe 1976), suggesting a highly localised distribution of this species. 4.2. ECHINODERMATA: CRINOIDEA (CAAB NUMBERS F.R. McEnnulty, et al. 24 250##### AND 99250###) 252#### AND 99250###) A) NUMERICAL SUMMARY A) NUMERICAL SUMMARY Over 250 specimens of the Crinoidea from 39 species from 29 genera, 13 families and two orders were collected, and an additional 6 OTUs were only identified to higher level taxa. Thirty-five species could be identified as described species, two recognised as new (but as yet undescribed) and two remain unknown or uncertain (Table 3). Of the 39 Crinoidea species recorded, 30 occurred at one station only, while the two most common species occurred at six stations; Phanogenia brevicirra (25030043) from Kalbarri to Point Cloates and Comatula pectinata (25030030) from Jurien to Barrow (Appendices 1, 2). Australia and the Indo-Pacific Ocean have a diverse number of well studied Echinoidea species that occur in a wide range of habitats where they are often a conspicuous component of the marine fauna, making them easily identifiable (Miskelly 2002). This is reflected in the results of this survey. More than 400 specimens of Echinoidea identified as only 35 species from 26 genera, 14 families and nine orders were collected. During the survey 31 described species were identified, only two new species were distinguished and two remain uncertain (Table 3). Of the 35 Echinoidea species recorded, 14 occurred at one station only, while the most common, Prionocidaris baculosa (25202017) occurred at eight stations from Kalbarri to Ningaloo (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES As only 5% of the Crinoidea are uncertain species and 5% are new species, the following biogeographical summary applies to the majority of species, the 90% (35 species) identified as previously described species (Table 4). Five species (14%) are Australian endemics and two of these (6%) are Western Australian endemics. The remainder (61%) have an Indo-West Pacific affinity or Indian Ocean only (6%), Southern Ocean or sub-Antarctic (11%) affinity or are cosmopolitan (3%) (Table 4). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES As only 6% of the Echinoidea are uncertain species and 6% are new species, the following biogeographical summary applies to the majority of species, the 89% (31 species) identified as previously described species (Table 4). The data reveals 6 (19%) are Australian endemics, and only one of these species (3%) is a Western Australian endemic. The remainder of the species have an Indo-West Pacific (71%), Southern Ocean or sub-Antarctic (6%) or Indian Ocean (3%) affinity. At least five are new species records for Australia, 11 are new records for Western Australia, and several others could only be identified to genus or family and may represent new species. The vast majority of specimens were comatulids (unstalked crinoids) with only one stalked crinoid (Bathycrinidae) collected. Crinoid identification was problematic, as many characters of the arm and cirri, traditionally used to separate species, are related to size of the animal and the ecological conditions prevailing at the collection site. Tissues from species collected by the SS200510 survey are being analysed by Eléaume and Hemery (Muséum National d’Histoire Naturelle de Paris; pers. comm.) using molecular methods to further understand their relationships. One species, provisionally identified as Stiremetra breviradia, was bioluminescent. Two species collected during this survey, Neometra conaminis and N. gorgonia, were originally described from this region by A.H. Clark (1914) from one of the few deep-water trawling collections on the FIS Endeavour off the mid-west coast of Western Australia (Fremantle to Geraldton in 146–219 m depths) in 1912. Over half of the urchin species were found only in the 100 m depth samples (with a few also recorded at the 200 m sites). Several Cidaridae species were only collected at 400 m depth from Mentelle and Bunbury (Rhopalocidaris gracilis and R. hirsutispina – no images) and at the Houtman Abrolhos Islands (Stereocidaris sceptriferoides) (25202023). The most widespread species was Caenopedina mirabilis (25220003), which was found at nine sites from Point Hillier to Ningaloo but all at 400 m depth except for the northernmost site where it occurred at 100 m (Appendices 1, 2). 4.3. ECHINODERMATA: ECHINOIDEA (CAAB NUMBERS The deep water southern temperate species, Dermechinus horridus and Gracilechinus multidentatus Three are new species records for Australia, while 15 are new records for Western Australia. The high number of new records for Western Australia (50% of the echinoid species recorded from the survey) reflects the lack of knowledge of the deep-sea fauna of the western continental margin of Australia. Of these new records for Western Australia, five are extensions to the known distributions of Australian endemic species. EDs PLEASE ADVISE DEEPWATER MEGABENTHOS OF SOUTH-WESTERN AUSTRALIA (25246002), were only recorded from the 1,000 m sites on the south coast from Point Hillier, Albany and Bald Island. While the deep water species, Phormosoma rigidum (25206002), was recorded at 700 m and 1,000 m on the south coast, it was also found at 700 m at the Houtman Abrolhos Islands and southern Ningaloo reflecting its Indo-Pacific distribution. Araeosoma owstoni (25205002) was the only deep water tropical echinoid species found at 700 m at southern and northern Ningaloo stations and but it was also found at 1,000 m in Perth canyon (Appendices 1, 2). 4.4 ECHINODERMATA: HOLOTHUROIDEA (CAAB NUMBERS 254##### & 99250###) A) NUMERICAL SUMMARY Our knowledge of the deep water Holothuroidea in Australian waters is poor and is reflected by the large number of new species found in this survey. A progressive systematic revision of known material incorporating molecular phylogenetic data is underway and more new species will certainly emerge. More than 1,300 specimens of Holothuroidea were collected on this survey representing 43 species and 27 genera in 12 families and 5 orders. During the survey 25 described species were identified, 17 new species were distinguished and one remains uncertain (Table 3). Two new species of the family Holothuriidae have been described from this survey, extending from subtropical to warm temperate locations. This is noteworthy since the vast majority of the 157 species in the family Holothuriidae are recorded from shallow tropical waters predominantly on coral reefs <50 m depth. The discovery of Holothuria (Panningothuria) austrinabassa O’Loughlin, 2007 (in O’Loughlin et al. 2007) represents the southern-most record for the family Holothuriidae in the world (25416062). Morphological and genetic analyses of the other new species, Holothuria (Halodeima) nigralutea O’Loughlin, 2007 (in O’Loughlin et al. 2007) found it to be a very recent offshoot of the wide-ranging Indo-West Pacific species H. (Halodeima) edulis. The etymology of this new species refers to the distinctive black and yellow colouring of the live individuals (25416063). Of the 43 Holothuroidea species recorded, 25 occurred at one station only, while the most common, Pseudostichopus hyalegerus (25418012) occurred at 20 stations from Bald Island to Abrolhos (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES As only 2% of the Echinoidea are uncertain 25 species and 40% are new species, the following biogeographical summary applies to the 58% (25 species) identified as previously described species (Table 4). The Holothuroidea data reveals none are Australian endemics. Twenty (80%) of the species have an Indo-West Pacific affinity, with the remainder with a widespread Southern Ocean or sub-Antarctic (8%) or cosmopolitan distribution (8%). A single species was previously recorded from the Indian Ocean only (4%) affinity (Table 4). At least 11 species are new records for Australia, 19 are new records for Western Australia of which two species are range extensions of Australian endemics. The recent revision of the genus Psolium (O’Loughlin and Maric 2008) described six new Australian species, including Psolium mccallumae collected during this survey, and re-assigned Psolus parmatus to Psolidium (25404011). The range of the latter species, described from the Siboga Expedition and previously known only from the Banda Sea in Indonesia, now extends south to Ningaloo in northwestern Australian waters. Psolium mccallumae is known only from the material collected at 100 m depth off Point Cloates (O’Loughlin and Maric 2008). 4.5. ECHINODERMATA: OPHIUROIDEA (CAAB NUMBERS 2516#### AND 99250###) A) NUMERICAL SUMMARY Over 4,300 specimens of the Ophiuroidea were collected by this survey including 146 species from 66 genera, 14 families and two orders. Of these 101 described species were identified and at least 39 are undescribed, and probably new to science, while six remain unknown or uncertain (Table 3). One new species, Ophiomyxa crinita Franklin and O’Hara, 2008, has been described from this material, to date (see Appendix 2: image 25166006). Of the 146 Ophiuroidea species recorded, 45 occurred at one station only, while the most common, Ophiura ooplax (25176039) occurred at 23 stations from Bald Island to Ningaloo. Ophiomusium relictum occurred at 19 stations in a more restricted temperate distribution from Bald Island to Jurien (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES As only 4% of the Ophiuroidea are uncertain species and 27% are new species, the following biogeographical summary applies to the 69% (101 species) identified as previously described species (Table 4). The Ophiuroidea data reveals only 11% are Australian endemics, and none are Western Australian endemics. The remainder have fairly 26 widespread distributions with 66 species (65%) with an Indo-West Pacific affinity, (11%) a Southern Ocean or sub-Antarctic Indian Ocean (10%) and 10% are cosmopolitan. A single species has previously only been recorded from the Atlantic Ocean (1%) and two species from only the Indian Ocean (2%). Biogeographically, the western continental margin was found to be an overlap zone of tropical and temperate faunas with a few species being endemic to the area. At least 16 are new species records for Australia, while 48 are new records for Western Australia, of which Amphiura dolia (25191025) collected at Kalbarri and Ningaloo, is a considerable range extension of an east coast Australian endemic previously found from Tweed Heads, NSW to Bass Strait. The collection extended the southernmost records of tropical species – e.g. Amphilimna granulifera, A. transacta (25185063) and Sinophiura multispina – and northernmost records of temperate species – e.g. Ophionereis schayeri (25179009), Ophiothrix caespitose (25192002). Ophiactis brevis, previously known only from the shallows at its type locality near Darwin at 5–10 m depth and the Dampier Archipelago in 13–20 m depth (Marsh and Morrison 2004) was collected from northern Ningaloo in 160 m depth (Appendices 1, 2). Of particular interest was the fauna from the deep-water seamounts near Albany that supported a Solenosmilia variabilis coral cover. Many of the ophiuroid species found at this site were previously recorded from Solenosmilia reef on deep-water seamounts south of Tasmania and on the Chatham Rise, west of New Zealand (O’Hara et al. 2008b). At least 30 species tested from the first half of the voyage (the temperate sites from Albany to Perth) were found to be bioluminescent (Mallefet and O’Hara, unpublished data; for techniques see: Mallefet et al. 2008). 5. CRUSTACEA: DECAPODA (CAAB NUMBERS 28###### & 99280###) A) NUMERICAL SUMMARY These data have been previously reported (Poore et al. 2008) but subsequent taxonomic changes and new species names are reported here. Over 6,200 specimens of the Decapoda, identified as 521 species and 267 genera from 75 families were collected. Of these species, 340 were recognised as previously described species, 158 new species were determined and for 23 OTUs the identifications were uncertain (Table 3). Within the described species, Retropluma cf. quadrata, doubtfully identified as the West Pacific species, is the first Australian record of the family Retroplumidae (Poore et al. 2008). F.R. McEnnulty, et al. Twelve new species have been described since Poore et al.’s (2008) report, using material collected during this survey, a process that is continuing. Of the Brachyura, new species include Oxypleurodon wilsoni Richer de Forges and Poore, 2008 and Rochinia annae Richer de Forges and Poore, 2008. Of the Caridea, Lebbeus clarehannah McCallum and Poore, 2010 is described from 400 m off Bald Island; the holotype of this distinctly coloured species is shown in Appendix 2: see image 28767804. Pseudoclimenes holthuisi Bruce, 2008 is described from 100 m off Jurien. Also recently described is Lissosabinea lynseyae Taylor and Collins, 2009 (28781020) from 400 m off Bunbury. In a recent review of the Axiidae, Poore and Collins (2009) described the following four new species from single locations from this survey: the new genus and species, Australocaris pinjarup from 400 m off Bunbury, Acanthaxius gathaagudu from 400 m off Shark Bay and Acanthaxius ningaloo from 200m off northern Ningaloo. Images of these holotypes are in Appendix 2: see 28801806, 28801803, and 28801804, respectively. One new species, Calastacus myalup Poore and Collins, 2009 is described from 400 m off Bunbury and is a new record for the genus in the Indian Ocean as well as Australia. Of the Anomura, Munidopsis comarge Taylor, Ahyong and Andreakis, 2010 (28840170) has been described from 900 m off Albany. Specimens from this survey in southern Western Australia were included in Ahyong’s (2010) review of the Lithodidae which resulted in the new species, Lithodes rachelae (28836014), collected from 850 m to 1,000 m between Albany and Perth Canyon and Paralomis poorei (28836010) recorded at 900 m off Albany (Appendices 1, 2). Neopilumnoplax nieli (28917007) is also newly recognised from recent deep water collections in south-east Australia and New Zealand (Ahyong 2008) and was collected from Albany to Two Rocks collected from 200– 900 m depths. Since Poore et al.’s (2008) report several species have been identified, redetermined or moved to other genera (Appendix 1). The following are replacement names: Engystenopus palmipes, Philoceras incisus, Calaxius acutirostris, Bouvieraxius keiensis, Paraxiopsis pumilus, Planaxius brevifrons, Ciliopagurus shebae, Munida gordoae, Paragoneplax serenei, Neogoneplax renoculis, Stereomastis auriculatus and Stereomastis suhmi. For example, Philocheras MoV5422 from Poore et al.’s (2008) has now been identified as P. incisus and is the first record of this species in Australian waters (Taylor 2010) (see Appendix 2: image 28781804). Of the 521 Decapoda species recorded, 238 species occurred at only one station. The most frequently recorded species of the entire survey, the hermit EDs PLEASE ADVISE DEEPWATER MEGABENTHOS OF SOUTH-WESTERN AUSTRALIA crab Paguristes aciculus (28827077) occurred at 27 stations. This species was found in depths of 95 m to 554 m at sites from Bald Island to Ningaloo (Appendices 1, 2). B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES As only 5% of the Decapoda are uncertain species and 30% are new species, the following biogeographical summary applies to the 65% (340 species) identified as previously described species (Table 4). The data reveals 21% (71 species) are Australian endemics, but only 4% (13 species) are Western Australian endemics. The majority of the species have widespread distributions, 68% (232 species) have an Indo-West Pacific affinity, 4% widespread Southern Ocean or sub-Antarctic affinity and 4% cosmopolitan in their distribution. The remaining 3% have previously only been recorded from the Indian Ocean. At least 74 are new species records for Australia, 154 are new records for Western Australia. Of these, 20 species represent range extensions of Australian endemics to the west. Poore et al. (2008) detailed and summarised all new Australian records, new records for Western Australia and new records for southern Western Australia. Of the commercially fished species collected during the survey, Ibacus alticrenatus, the White-tail Bug (28821001) was the most common, occurring around 400 m. The commercial crab Hypothalassia acerba was collected only twice around 200 m while the other main large benthic crustaceans of commercial interest; Panulirus cygnus, Jasus edwardsii, Pseudocarcinus gigas and Chaceon albus (formerly confused with C. bicolor see Davie et al. 2007) were not collected at all, this is most likely an artefact of the types of sampling gear (no baits) used and terrain targeted. Only one commercial species of prawn, Haliporoides sibogae (28714005) was collected and this was numerous at 400 m. Several species of scampi (Nephropidae) were also collected at this depth (Appendices 1, 2). 6. PYCNOGONIDA (CAAB NUMBERS 33###### AND 99330###) A) NUMERICAL SUMMARY Forty specimens of the Pycnogonida from 17 species in 11 genera and five families were collected. Of these 11 could be identified as described species, four recognised as new species and two remain uncertain (Table 3). The new species, Hedgpethia calva, Tanystylum zuytdorpi, Pseudopallene difficile and Paranymphon bifilarium 27 were described by Arango (2009). Photographs of the holotypes for the first two species can be viewed in Appendix 2: 33014024 and 33012054. Of the 17 species of Pycnogonida recorded, 14 occurred at one station only, while the most common, Pallenopsis cidaribatus (33020010), occurred at four stations in tropical waters from Shark Bay to Ningaloo (Appendices 1, 2) B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES As only 12% of the Pycnogonida are uncertain species and 24% are new species, the following biogeographical summary applies to the 64% (11 species) identified as previously described species (Table 4). The data reveals 45% (5 species) are Australian endemics and of these 12% (2 species) are Western Australian endemics. The remainder have an IndoWest Pacific affinity 45% or are cosmopolitan (6%) in their distributions. Five species are new records for Western Australia. Three of these new species records for Western Australia are range extensions of Australian endemics. Three species were collected only in the deep waters off the south coast of Western Australia: Cilunculus sp. 1 from 700 m off Albany, Colossendeis colossea from 1,000 m off Port Hillier, and Hedgpethia calva from 1,000 m off Bald Island. The other 14 species were collected at only 100 m depths at a range of temperate and tropical sites (Appendix 1). 7. TUNICATA: ASCIDIACEA (CAAB NUMBERS 35###### AND 99350###) Over 450 specimens of the Ascidiacea from 77 species, 25 genera, 11 families and two orders were collected (Table 3), from 34 of the shallower surveyed sites, with 21 100 m sites, seven 200 m sites and six 400 m depth sites recording specimens. During the survey, 52 described species were identified, 21 new species were described and four remain uncertain (Table 3). The majority of the new species were collected from the southern continental margin of Western Australia and the new species have been described by Kott (2008). Prior to this survey there were 50 species known from the shallower coastal waters of Western Australia and adjacent areas (Hartmeyer 1919; Hartmeyer and Michaelsen 1928; Michaelsen 1930; Kott 1985, 1990, 1992, 2001, 2005a, 2005b). Only 21 of these previously known species were collected at more than one site on this survey of the deep shelf and slope. Of the 77 Ascidiacea species recorded, 49 occurred at one station only, while the most common species, Sigillina australis (35021011) occurred at seven stations from Albany to Carnarvon (Appendices 1, 2). F.R. McEnnulty, et al. 28 Solitary species were rare and the collection was dominated by colonial species of the families Didemnidae and Polyclinidae. Species with flexible stalks were not often collected suggesting some bias associated with the collection method. B) BIOGEOGRAPHICAL DISTRIBUTIONS OF PREVIOUSLY DESCRIBED SPECIES As only 5% of the Ascidacea are uncertain species and 27% are new species, the following biogeographical summary applies to the 68% (52 species) identified as previously described species (Table 4). The data reveals 38% (20 species) are Australian endemics but only 8% (2 species) are Western Australian endemics. The majority of the species, 54% (28 species) have an Indo-West Pacific affinity, while a single species recorded a Southern Ocean or sub-Antarctic (4%) or Indian Ocean (4%) or Atlantic Ocean (4%) affi nity or cosmopolitan distribution (4%). A total of two species are new records for Australia, five are new records for Western Australia including Synoicum sphinctorum, a range extension of an Australian endemic species. This previously unsampled diverse offshore ascidian fauna extends the known biogeographical limits of many species around the Australian coastline. Species known from the tropical north have their range extended to the south, either to the central west coast (Pseudodistoma australe, Synoicum macroglossum, Aplidium caelestis, A. crateriferum, A. solidum, Polysyncraton millepore, Didemnum jedanense and Trididemnum sibogae) or to the south-western corner (Polysyncraton pavimentum, Didemnum ossium and D. perplexum). The distributions of the South Australian species, Pseudodiazona longigona and Leptoclinides fungiformis, has been extended westward to the continental shelf off Albany in 100 m depth. Two new species records for southwest Western Australian include the tropical, Herdmania momus, known from the western Pacific and Red Sea (also new open sea-floor habitat record at depths to 400 m) and Synoicum laboutei, formerly restricted to Malagasy in the western Indian Ocean. Further details on this ascidian fauna can be found in the comprehensive paper by Kott (2008) and details on a subsequent deepwater survey of the north-western continental margin in Kott (2009). DISCUSSION Taxonomic study of the first regional scale collection of deepwater megabenthic invertebrates from Australia’s western continental margin (100 m to 1,500 m depths and between ~21–35ºS latitude) reveals a previously undiscovered high level of species richness and novelty in the fauna. In the six major invertebrate groups targeted for this study – Demospongiae: Porifera, Octocorallia: Cnidaria, Mollusca, Echinodermata, Decapoda: Crustacea and Ascidiacea: Tunicata – 19,000 specimens yielded 2,021 species of which only 44% are described. One-quarter of all species identified are new records for Australian waters and over one-third are new records for Western Australian waters. From this survey material 42 new species have already been described: O’Loughlin (2009); Asteroidea, one species; Franklin and O’Hara (2008): Ophiuroidea, one species; O’Loughlin et al. (2007) and O’Loughlin and Maric (2008): Holothuroidea, three species; Bruce (2008), Richer de Forges and Poore (2008), Poore and Collins (2009), Taylor and Collins (2009), Ahyong (2010), McCallum and Poore (2010) and Taylor et al. (2010): Decapoda, 12 species; Arango (2009): Pycnogonida, 4 species; and Kott (2008): Ascidiacea, 21 species. The high numbers of new records clearly reflects the lack of previous deep-sea research in this region, but also highlights the paucity of taxonomic knowledge or the lack of clarity in the literature for some groups. More than 50% of the species of Octocorallia, Antipatharia, Bivalvia, Cephalopoda, Gastropoda, Scaphopoda and Demospongiae collected are uncertain identifications. Further taxonomic work would ideally include revisions of some of the less well studied deep-sea taxa within otherwise well-known groups such as the Bivalvia. Demosponges dominated in terms of biomass, but only 5% of species collected were described species. This reflects the lack of knowledge and potentially higher rate of endemism of this sessile taxonomic group. In contrast, 89% of echinoids, a more motile group with widespread distributions, could be identified as described species. Overall, distributional patterns of described invertebrate taxa show the western margin is an overlap zone of tropical and temperate faunas. Knowledge from relatively well-known taxa confirmed, firstly, that many south-eastern Australian species were also recorded from Western Australia for the first time, and secondly, that the geographic distributions of many tropical/ sub-tropical species extend to temperate latitudes. This can be illustrated by the relatively well known southern Australian Decapoda (Poore 2004), for which this survey extended the known distributions of 62 documented species, and added 76 species to the temperate fauna – a 9.4% increase (Poore et al. 2008). Patterns in other groups indicated northwards extensions to their known distributions – an example being the penetration of several predominantly cold water asteroid families into deep waters of tropical latitudes. The distributions of the 876 described species showed the strongest biogeographical pattern of the deep continental shelf fauna was an affinity with EDs PLEASE ADVISE DEEPWATER MEGABENTHOS OF SOUTH-WESTERN AUSTRALIA the wider Indo-West-Pacific region (61% of species). Relatively few taxa appeared to be endemic to either the Indian Ocean (4%) or to Western Australia (5%) but 25% of species are endemic to Australia. This may be an underestimate given the high number (727) of uncertain species that could not be identified as known or new species until further taxonomic comparisons are undertaken, and the newly determined 396 species which as yet have not been found elsewhere in the world. Confirmation of this apparent endemism in such a poorly known region requires further taxonomic examination. This is epitomised by the Demospongiae of which the vast majority (95%) of the 372 species are uncertain or new. In one wellstudied and species rich taxon, the Ophiuroidea, the western margin was found to be an overlap zone of tropical and temperate faunas with few endemic species confined to Western Australian waters. Apparent rarity is high but typical of surveys of this kind, that is with few samples spread over a wide geographic range (e.g. fishes – Williams et al. 2001). More than half of the species were collected from only one location. However, this is due, in part, to undersampling of species that may be of limited distribution or at low densities or difficult to catch with the sampling gears used. In addition, while this survey targeted the megabenthos >25 mm, some smaller macrofaunal specimens and pelagic cephalopods were incidentally collected, identified and included in this checklist. These macrofaunal data are a valuable record of presence in the previously unstudied western continental margin of Australia but not an accurate representation of the population. Large intervals (typically of about 60 nautical miles) separated the 19 sites along the ~2,000 km of continental margin surveyed, and there was insufficient replication at depths within sites to distinguish abundance from sampling efficiency or the degree of patchiness (Williams et al. 2010). The low density of samples, together with an unequal sampling intensity across sites, means that patterns of abundance must also be interpreted with care. While the sampling design aimed to systematically target soft and hard substrates at all of the sites on the 100 m and 400 m depth horizon, swath mapping of relatively large areas of seabed (10s to 100s km2 per site) confirmed that both substrate types were not present at every site. On the other hand, mapping did identify special features at some sites enabling them to be sampled more intensively. For example, 13 collection stations at Ningaloo targeted a series of hard substratum types associated with drowned coral reefs and with rocky substratum within canyons. 29 As a result of the collections taken on the SS200510 survey and the continuing taxonomic work, we now have a substantially increased k nowledge of the megabenthic invertebrate fauna from the deep western continental margin of Australia. All the invertebrate megabenthos collected during this survey are lodged in museums around Australia (including the ethanolpreserved material suitable for genetic analysis) and is available for further study. Together with a high quality data set on fishes collected in 1991 (Williams et al. 2001), these benthic invertebrate biodiversity data will make a large contribution to the Regional Marine Planning for the South West Region and inform the design of a representative system of marine protected areas.
