Description
Penion ormesi is a large to very large species of siphon whelk.[4] P. ormesi is benthic, and typically inhabits soft-sediments on the continental shelf.[5]
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]
