Pneumodermatidae is a family of sea angels, or small floating predatory sea snails or sea slugs. They are pelagic marine heterobranch opisthobranch gastropod mollusks in the order Gymnosomata.

These small pelagic snails 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.

A more comprehensive discussion can be found under the entry sea angel.
