Carinaria

Carinaria is a genus of medium-sized floating sea snails, pelagic gastropod molluscs in the family Carinariidae.

Anatomy

The cylindrical and elongate body consists of three parts : a short proboscis, a well-developed trunk and tail region of variable size. The size of this tail goes from very small in Carinaria galea to very large in Carinaria cristata. The well-developed swimming fin is located in both sexes at the back of the trunk and has at its back margin a small fin sucker. The right tentacle is small or vestigial. The cuticle is thick and gelatinous. The shells are known as “Venus slippers.”
