''Pelagia benovici'' (Piraino, Aglieri, Scorrano & Boero, 2014) is a jellyfish in the family Pelagiidae, along with Pelagia noctiluca. In Latin, ''Pelagia'' means "of the sea". The team who discovered this jellyfish named it benovici, after a late colleague, Adam Benovic. == Classification == ''P. benovici'' is an animal, thus non-photosynthetic, multicellular eukaryote, in the phylum Cnidaria. Being a cnidarian it is diploblastic, having an ectoderm and endoderm separated by an ectodermally derived mesoglea that can be cellular or acellular. It is a member of the cnidarian class Scyphozoa and adapted to a pelagic mode of life. Whereas most scyphozoan jellyfish (also called scyphomedusae) have a complex life cycle with both the pelagic (swimming) jellyfish, or medusa, stage and a bottom-living polyp stage, ''Pelagia'' has adapted in such a way that the polyp stage is absent, thus direct development exists. The male and female jellyfish spawn respectively sperm and eggs, which develop directly into young jellyfish. ''Pelagia'', like other jellyfish in the scyphozoan order Semaeostomeae are mainly distinguished from the other orders by having simple oral arms with frilled or folded lips. The order semaestomae comprises three families: Pelagiidae, Cyaneidae,and Ulmaridae, distinguishable by the following characters: *1. Gastrovascular cavity divided by radial septa into rhopalar and tentacular pouches. * *a. Pouches simple and unbranched – ''Pelagiidae'' * *b. Pouches branched – ''Cyaneidae *2. Gastrovascular system in form of unbranched and branching canals, or with anastomosing radial canals – ''Ulmaridae'' In addition, members of the ''Pelagiidae'' have no ring canal, and the marginal tentacles arise from umbrella margin. 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「Pelagia benovici」の詳細全文を読む スポンサード リンク
