... Parapterois is characterized by 2 anal-fin spines (vs. 3 in other pteroine genera); and the caudal fin with elongate, filamentous rays in the upper and lower lobes (vs. truncate or rounded without elongate rays in other pteroine genera) (Poss 1999;Matsunuma et al. 2013bMatsunuma et al. , 2016Matsunuma et al. , 2017Matsunuma and Motomura 2014a, b, 2015a, b, 2018. In Parapterois, the interorbital, coronal, and parietal ridges are all interconnected, forming a low ridge, whereas ridges formed by these elements are not conjoined in other pteroine genera (except Ebosia). ...

Although sexual dimorphism in head spine condition has been reported in Brachypterois and Ebosia (see Matsunuma et al. 2013b;Matsunuma andMotomura 2014a, 2015a), examination of 27 male and female specimens of Pa. heterura failed to identify any sexual dimorphism in morphological characters, including head spine condition and relative eye position. ...
A taxonomic revision of the genus Parapterois (Scorpaenidae: Pteroinae) resulted in recognition of three valid species, Pa. heterura (Bleeker 1856) (type locality: Indonesia), Pa. macrura (Alcock 1896) (India) and Pa. nigripinnis (Gilchrist 1904) (South Africa). Previously regarded (as Pterois nigripinnis) as a junior synonym of Pterois heterurus Bleeker 1856, the last-mentioned is readily distinguishable from its congeners by having interrupted or wavy white lines and/or spots present below the eye (vs. solid white lines in congeners) and the pectoral-fin axilla with many white spots (vs. spots absent). Although Pa. macrura is most similar to Pa. heterura, the two species can be distinguished from each other by several morphometric characters, including the relative position of the orbit (with respect to the top of the nasal protuberance and the first dorsal-fin base), and the number of spinules on the cheek scales. Parapterois heterura is widely distributed in the eastern Indian and western Pacific oceans, whereas Pa. macrura and Pa. nigripinnis are restricted to the Arabian and Laccadive seas, and the southwestern Indian Ocean (east coasts of Mozambique and South Africa), respectively. Pterois jordani Regan 1905, Ebosia starksi Franz 1910, Pterois tanabensis Tanaka 1918 and Ebosia pavo Schmidt 1931, all described from Japan, are regarded as junior synonyms of Pt. heterurus. Pterois natalensis von Bonde 1923 (type locality: South Africa) is synonymized under Pt. nigripinnis. Lectotypes are designated for Pt. macrura and Pt. nigripinnis, and a key to species of Parapterois is provided.
... The scorpionfish dwells in a wide range of aquatic environments including tropical (Adrim et al. 2004), sub-tropical (Motomura et al. 2004) and temperate (Motomura et al. 2006) regions but are native to the Indian and Western Pacific Ocean. Currently, the genus Brachypterois has three recognized species of which the Australian sawcheek scorpionfish, Brachypterois curvispina is only reported from the Australian coast (Coral Sea) (Matsunuma et al. 2013) and the Indian Ocean (Naranji and Kandula 2017), another two species are Brachypterois serrulifer and Brachypterois curvispina. ...

The composition and ichthyofaunal diversity of the Bay of Bengal and its adjacent coast have been being explored with time. Australian sawcheek scorpionfish, Brachypterois curvispina is a newly reported species in Bangladeshi water recorded from the St. Martin Island (coral reef) off the Bay of Bengal coast. The identity of this species was confirmed by comparing it with the published morphological description of a specimen reported from the Australian coast. The presence of posteriorly directed lachrymal spines is the key character of this species. Its preferred food items were observed small fish, shrimp, lobster, crab, and some aquatic insects. The dispersal of this species in this geographical area illustrates a considerable expansion of its distributional range, the previously reported Australian coast which is far off from the present record. Although the actual cause of dispersal is unexplored, climate change and global warming are assumed to stretch out the species distribution range. This discovery of Brachypterois curvispina provides a new non-native species record in the coral reef of Bangladesh and represents the northern-most dispersal in the Indo-Pacific region.
... Lionfishes are part of the Scorpaeniformes order, characterized by bottom dwelling fishes commonly found in tropical and temperate waters where they are active predators of invertebrates and fishes (Hamner et al., 2007;Freshwater et al., 2009;Morris, 2009;Betancur-R et al., 2011). The subfamily Pteroinae comprise 27 species in 5 genera: Pterois (12 species), Dendrochirus (6 species), Ebosia (4 species), Brachypterois (3 species), and Parapterois (2 species) (Matsunuma et al., 2013;Wilcox et al., 2018). Hybridization was recently reported between two members of the genera (P. ...

Σε αυτή την πτυχιακή εργασία παρουσιάζονται τα αποτελέσματα της έρευνας που διενεργήθηκε για το λεσσεψιανό είδος Pterois miles (Bennet, 1828), το οποίο εμφανίστηκε στα νερά της Ρόδου το 2015. Αυτή η προκαταρκτική έρευνα περιελαμβάνει μια σειρά αποτελεσμάτων που αφορούν τα μορφολογικά χαρακτηριστικά και τις διατροφικές προτιμήσεις του είδους. Για τον σκοπό της εργασίας χρησιμοποιήθηκαν 42 άτομα που αλιεύθηκαν κατα μήκος της θαλάσσιας περιοχή της Ν. Ρόδου από το Μάϊου του 2016 έως τον Νοέμβρη του 2017. Τα δείγματα διαχωρίστηκαν ως προς το φύλο, το μέγεθος και την εποχή σύλληψης για την εξέταση της πληρότητας/κενότητας του στομαχικού περιεχομένου. Σε σχέση με το φύλο χωρίστηκαν σε Αρσενικά (21), Θηλυκά (12) και Μη προσδιορίσιμα άτομα (9). Ως προς το μέγεθος το ελάχιστο μήκος ήταν 148,8 εκατοστά και το μέγιστο ήταν 315,20 εκατοστά. Η συσχέτιση σταθερού μήκουςολικού βάρους έδειξε ότι τα αρσενικά άτομα ήταν κατα πλείστον εύσωμα, τα θηλυκά είχαν αλλομετρική αρνητική σχέση ενώ το σύνολο των ατόμων έδειξε ισομετρική σχέση. Απο το σύνολο του δείγματος τα 32 άτομα παρουσίασαν ενδιαφέρον ως προς την πληρότητα. Για την ανάλυση του στομαχικού περιεχομένου χρησιμοποιήθηκαν τρείς μεθόδοι, η αριθμητική μέθοδος (Ν%), η μέθοδος συχνότητας εμφάνισης (F%) και η βαρομετρική μέθοδος (W%). Στην προσπάθεια προσέγγισης των τροφικών ειδών ολιστικά έγινε με την χρήση δύο δεικτών, η χρήση των οποίων συνέτεινε όχι μόνο στην καταγραφή της θέσης που καταλαβάνουν στο διαιτολόγιο αλλά και στην ιεράρχηση τους ανάλογα με τις τροφικές προτιμήσεις του ψαριού: ο δείκτης σχετικής σπουδαιότητας (IRI) και ο δείκτης του κύριου τροφικού αντικειμένου (MFI). Η τελική αξιολόγηση του στομαχικού περιεχομένου έδειξε ότι τα άτομα του είδους P.miles (Bennet,1828) τρέφονται κυρίως με ψάρια (Actinopterygii) και και οι κύριες τροφικές ομάδες ήταν οι γωβιοί (Gobiidae), και οι καλογρίτσες(Chromis chromis, Pomacentridae) και δευτερεύοντα με τα ασπόνδυλα, γαρίδες, κεφαλόποδα κλπ

Juvenile members of Ebosia, however, have a spine along the upper margin of the opercle (Matsunuma & Motomura 2015a, 2016b, and those of Parapterois have a spine along the lower margin of the opercle (Matsunuma & Motomura 2022). Members of Brachypterois have a spine on the upper margin, like those of Ebosia, and may or may not have a spine (typically subdermal, if present) on the lower margin (Matsunuma et al. 2013). the "spine-like" structures near the outer margin of the opercle that we noted in Kojima's (2014) illustration of a 11.5 mm D. zebra (Fig. 6b), if "spines," are resorbed during transformation because 14.0-15.0 ...
... the presence or absence of nuchal spines can also be used to distinguish some pteroine genera. As previously noted, postflexion and transforming larvae of P. volitans and the four Dendrochirus possess nuchal spines, as do juveniles of members of Parapterois, whereas juveniles of Brachypterois and Ebosia lack nuchal spines (Matsunuma et al. 2013;Matsunuma & Motomura 2015a, 2016b, 2022.

Despite the threat that lionfishes pose to non-native marine ecosystems worldwide, their early life stages (ELS) remain difficult to distinguish from morphologically similar taxa due to inadequate descriptions and poorly defined taxonomic characters. Two members of the Indo-Pacific marine assemblage commonly known as lionfishes, zebrafishes, firefishes, turkeyfishes, and butterfly-cods (Scorpaeniformes: Scorpaenidae: Pteroinae) are invasive in the Western North Atlantic (WNA). Here, we describe the ELS of Pterois volitans, Dendrochirus barberi, and two transforming larvae and an early juvenile of D. hemprichi; review the early development of D. zebra and a larva described as D. bellus; identify characteristics that distinguish P. volitans from the four members of Dendrochirus; and compile meristic and distribution data for all currently valid species of lionfishes worldwide based on recent revisions and updated nomenclature. We also briefly describe a small juvenile of two poorly known non-pteroine deep-water scorpaenids, and discuss characteristics that distinguish the five pteroines from non-pteroine scorpaenid genera in the WNA. Differences in relative length and elevation of the parietal and nuchal spines, and in pigmentation patterns distinguish P. volitans from the four members of Dendrochirus. Pterois volitans has parietal spines two or more times longer than the nuchals with both sets of spines oriented about 30° above the longitudinal axis of the head, whereas the four members of Dendrochirus have relatively short parietal and nuchal spines subequal in length that lay flatter against the cranium (i.e., elevation ≤15° above longitudinal axis of head). Transforming larvae of the four members of Dendrochirus also develop saddles of pigment along the dorsal and ventral margins of the body that P. volitans lacks at the sizes examined. One or more of the following suite of traits distinguish larvae of the five pteroines from those of non-pteroine scorpaenids and other morphologically similar taxa: the presence or absence of a “shield” of pigment over the dorsolateral margin of the visceral mass (may be reduced or augmented with scattered blotches of pigment in larger larvae of some taxa); the relative length, elevation, and placement of the parietal and nuchal spines; the presence or absence of a small slit behind the fourth gill arch; differences in pectoral-fin length, shape, and extent of pigmentation; the relative size, length, and placement of spines along the posterior shelf of the preopercle (PPO); and the presence or absence, number, and placement of spine(s) along the opercle.
Scorpionfishes belonging to families Apistidae, Scorpianenidae and Tetrarogidae are represented by many species in Pakistan, however, no comprehensive account of the known species of the area is ever published. Present study reports details of the scorpionfishes occurring in Pakistan based on published literature as well as through the collection of specimens from various parts of Pakistan. A total of 30 species were reported in this paper; of these, 1 species belonged to family Apistidae, 23 species belonged to Scorpianenidae and 6 species belonged to family Tetrarogidae. Of these, blacklash scorpionfish (Pontinus nigerimum) and broadbarred firefish (Pterois antennata) reported or the first time from Pakistan coast.
Lionfishes (tribe Pteroini) are eye-catching due to their distinct elongated fins and warning coloration. The monophyly of the Pteroini is supported by recent phylogenetic analyses. However, the interrelationships between inter-and intra-genera of the Pteroini are contentious. In this study, 5,335 bps of two mitochondrial and five nuclear genes were sequenced to reconstruct the phylogeny of lionfishes. Our analyses showed Dendrochirus and Pterois were both not monophyletic and divided into Dendrochirus I, II, and III clades (D. I, II, and III) and Pterois I and II clades (Pt. I and II), respectively. Pt. I was sister to the Pt. II + D. I clades. D. II was the sister group of the Ebosia + Parapterois clade. The D. III clade was at the base of the Pteroini, followed by the genus Brachypterois. Morphologically, we provided combinations of characters to distinguish all clades. According to the molecular and morphological data, we propose a revised taxonomy of the Pteroini. D. I and Pt. I hold the generic names of Dendrochirus and Pterois, respectively. Neochirus gen. n. is proposed as a new genus for the D. II clade. The genera Pteropterus Swainson, 1839 and Nemapterois Fowler, 1938 are revalidated for Pt. II and D. III, respectively.
We examined the reproductive biology of sawcheek scorpionfish, Brachypterois serrulata, collected from Visakhapatnam fish landing center (fishing area covered 16.98°-20.20°N, 82.19°-86.53°E). We studied the annual reproductive cycle, fecundity, size at first maturity, mode of spawning with periodical changes and histological preparations. Size distribution and size at sexual maturity were calculated as 108 mm TL for females. The mean gonado somatic index values of female increased rapidly from January to December, and reached its peak during January and February. The fecundity of the fish species is determined by the size and weight of the individuals. The fecundity varied from 1896 to 20,488, with an average of 5721.90 ova.
