The Cliopsidae, common name sea angels, are a taxonomic family of small, free-swimming sea slugs, pelagic marine opisthobranch gastropod mollusks in the order Opisthobranchia.
As is the case in all gymnosome pteropods, these sea angels lack a shell except during an early embryonic stage.
The small lateral wing-like flaps (parapodia) are used in a slow swimming mode. The foot is reduced to three small median lobes.
Genera and species within the family Cliopsidae include:
Genus Cliopsis Troschel, 1854
Genus Pruvotella
