Notobranchaeidae is a taxonomic family of floating sea slugs or "sea angels", pelagic marine opisthobranch gastropod mollusks.

The small pelagic snails of this family have no shell (except in the early embryonic stage). They are carnivores, equipped with swimming parapoda (fleshy winglike flaps), strong jaws and grasping tentacles, often with suckers resembling those of cephalopods.

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