The Pneumodermatidae are a family of sea angels, or small floating predatorysea snails or sea slugs. They are pelagicmarineheterobranchopisthobranchgastropodmollusks in the cladeGymnosomata.
These small pelagic snails lack shells (except in their early embryonic stage). They are carnivores, equipped with swimming parapoda (fleshy, wing-like outgrowths), strong jaws, and grasping tentacles, often with suckers resembling those of cephalopods.[1]
