It looks like a regular snail in the sense that its shell is a spiral shape.

This marine species occurs off New Zealand, off the coast of New Plymouth, Cape Palliser south to the Banks Peninsula.

It is also found on Chatham Rise and off Bounty and Campbell Island; also off Western Australia.

It makes its home in the mud and lives in its shell for all of its life.
