The Notobranchaeidae are a taxonomic family of floating sea slugs or "sea angels", pelagic marine opisthobranch gastropod mollusks. The small pelagic snails of this family have no shell (except in the early embryonic stage). They are carnivores, equipped with swimming parapodia (fleshy wing-like flaps), strong jaws, and grasping tentacles, often with suckers resembling those of cephalopods. ==Genera and species== Genera and species in the family Notobranchaeidae include: Genus: Notobranchaea Pelseneer, 1886 * ''Notobranchaea bleekerae'' van der Spoel & Pafort-van Iersel, 1985 * * Distribution : Oceanic * ''Notobranchaea grandis'' Pruvot-Fol, 1942 * * Distribution : Oceanic * * Length : 15 mm * ''Notobranchaea inopinata'' Pelseneer, 1887 * * Distribution : Oceanic * * Length : 5 mm * ''Notobranchaea macdonaldi'' Pelseneer, 1886 * * Distribution : Bermuda, Oceanic * * Length : 5 mm * ''Notobranchaea tetrabranchiata'' Bonnevie, 1913 * * Distribution : Oceanic * * Length : 16 mm 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Notobranchaeidae」の詳細全文を読む スポンサード リンク
