Penion is a genus of large sea marine snails, commonly known as siphon whelks, classified within the mollusc family Buccinidae, the true whelks.
Description
Siphon whelks are large, benthic marine snails, or whelks.[4] Most species inhabit soft sediments on the continental shelf.[5] Small shells and fossils of Penion can sometimes be confused with those of Aeneator.[6]
Distribution
Penion species are restricted to the Southern Hemisphere. Two extant species are currently classified in Australia[7][8] and six extant species are documented in New Zealand.[4]
Numerous fossil species are recorded in New Zealand,[6] Australia,[7] Argentina and Chile,[9][10] and Antarctica.[11][12]
Evolution
Penion is currently classified within Buccinidae, the family of true whelks.[13] A molecular phylogeny of Buccinidae based on the mitochondrial 16S rRNA gene suggested that Penion is a sister clade to Kelletia, a genus of whelks with extant species found in the Sea of Japan and in waters off of California, United States and Mexico.[13]
