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 Buccinidae, the true whelks.
Penion cuvierianus is a very large species of siphon whelk.[1][2] Shells vary between ivory and yellow in colouration.[2]
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.[3]
