Penion cuvierianus is a species of very large predatory sea snail or whelk, commonly called the flaring penion, a marine gastropod mollusc in the family Austrosiphonidae.^[1]

Description[edit]

Penion cuvierianus is a very large species of siphon whelk.^[2]^[3] Shells vary between ivory and yellow in colouration.^[3]

Recent genetic and geometric morphometric research using shell shape and size has demonstrated that a formerly recognised subspecies Penion cuvierianus jeakingsi is closely related to Penion ormesi, instead of Penion curierianus, and the taxon has been synonymised with P. ormesi.^[4]

Distribution[edit]

Penion cuvierianus is endemic to New Zealand.^[2]^[3] The taxonomic name is a reference to the type locality of Cuvier Island.^[2] The species has an abundant fossil record in the North Island of New Zealand.^[5]

The species occurs in the subtidal zone between depths of 20 and 200 metres.^[3]

Subspecies[edit]

These subspecies have been recognised:

Penion cuvierianus cuvierianus (Powell, 1927)^[2]^[5]

Subspecies brought into synonymy[edit]

Penion cuvierianus jeakingsi (Powell, 1947):^[2] synonym of Penion ormesi (Powell, 1927)^[4]
