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 winglike flaps (parapoda) are used in a slow swimming mode. The foot is reduced to three small median lobes.
A more comprehensive discussion can be found under the entry sea angel.
