Facelinidae

The family Facelinidae includes many of the larger Hawaiian aeolids. The body is usually elongate and the cerata are usually arranged in rows or arches. Most species feed on hydroids. However, the genus Favorinus specializes in eating the eggs of other opisthobranchs and the genus Phyllodesmium eats octocorals. Most species retain the nematocysts from their food in cnidosacs at the tips of their cerata and many also retain functional zooxanthellae, derived from their food, in specialized branches of the digestive gland. There are about 30 Hawaiian species in at least 14 genera (Antonietta, Caloria, Cratena, Facelina, Facelinella, Favorinus, Glaucus, Godiva, Herviella, Noumeaella, Phyllodesmium, Pleurolidia, Pteraeolidia and Sakuraeolis). The family was recently revised to include the families Cratenidae, Glaucidae and Pteraeolididae.
