Paedoclione is a genus of "sea angels", small floating sea slugs, pelagic marine opisthobranch gastropod mollusks.
They are shaped a little like angels, and have flapping "wings", hence their common name.
They are gelatinous, mostly transparent pteropods, and they only have shells in their embryonic stage.
External anatomy
The Clionidae use winglike flaps for rhythmical locomotion, as if flying in the sea. These "wings" are attached to the anterior part of the body. The posterior part is gelatinous and mostly transparent.
The orange visceral sac is confined to the anterior part.
Life habits
Mating is carried out ventrally for mutual fertilization. The following spring, this results in a free-floating, gelatinous egg mass.
