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.
