Description edit
Penion ormesi is a large to very large species of siphon whelk.[3] P. ormesi is benthic, and typically inhabits soft-sediments on the continental shelf.[4]
Recent genetic and geometric morphometric research using shell shape and size has demonstrated that a formerly recognised species Penion cuvierianus jeakingsi is closely related to Penion ormesi, and the taxon has been synonymised.[1] However, further genetic and morphological variation observed among these snails suggests that there may be further diversity within this lineage.[1]

Distribution edit
The species is endemic to New Zealand and is found in the Cook Strait and off the west coast of the South Island.[3] Fossils of the species are recorded from Wanganui.[5]
