Description
editPenion 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
editPenion 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]
