General Biology Additional Information	Little is known of the biology of this species. Early shell form is a spiral disc of about one whorl. Subsequent growth is tangential, slightly curved and tapering. As the shell tube lengthens, the animal's body only occupies the newer part of the shell near the mouth. A septum is laid down closing off the unwanted part of the shell which then breaks off, keeping the shell small, this is repeated throughout the animals life. It is presumably an adaptation to interstitial life.
