Description

Penion chathamensis is a very large species of Penion siphon whelk.[1] Although P. chathamensis has separate sexes, the species does not appear to exhibit secondary sexual dimorphism in shell shape or size.[2]

Distribution

Penion chathamensis is endemic to New Zealand.[1][2][3] The species is distributed off of the west coast of the South Island, and occurs on Chatham Rise and in waters surrounding the Chatham Islands[1][2][3] The latter location is the type locality, giving rise to the binomial name of the species.[1]

gollark: But... that's not communism.
gollark: Also, there's loads of space left in the republic which is occupied currently by oversized parks and excessively dense roads.
gollark: How would that work?
