The small planktonic pelagic snails of the family Thliptodontidae (Kwietniewski, 1910) lack a shell (except in their early embryonic stage).They are carnivores, equipped with swimming parapoda (fleshy winglike outgrowths), strong jaws and grasping tentacles, often with suckers resembling those of cephalopods.
