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

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.

[2] The shells are known as “Venus slippers.” The World Register of Marine Species includes the following species within the genus Carinaria:[1]
