The parapodia contain branches of the digestive gland and also function in respiration. Many species retain chloroplasts as kleptoplastids and some may show substantial variation in morphology based on differences in diet or associated chloroplasts. They may be either diurnal or nocturnal. There are at least 28 species known from Hawaii in four genera (Bosellia, Elysia, Plakobranchus and Thuridilla). The family Boselliidae has been sunk into Plakobranchidae. Thuridilla hoffae is listed for French Frigate Shoals from a pre-2006 cruise but we lack confirmation for the record.
