It is found in the South Atlantic Ocean and the Mediterranean Sea and has been introduced into the Black Sea, the Aegean Sea, the Sea of Azov and the Caspian Sea. It was first described by the French physician and zoologist Jean Guillaume Bruguière in 1789. ==Description== ''Beroe ovata'' grows to a total length of about . In shape it is roughly oval or cylindrical, but can be flattened like a mitten or deformed. At one end, known as the oral end, is the large mouth and at the other (aboral) end is a statocyst which has a sensory role and is involved in maintaining the animal's equilibrium. The body wall is composed of a gelatinous mesoglea sandwiched between two layers of cells. It is translucent and pale blue, or sometimes pale pink. On the exterior surface, eight longitudinal rows of cilia form the "combs", and it is these cilia, beating in unison, that propel the animal through the water. It usually moves with the mouth at the front but can reverse the direction of travel. This comb jelly has no tentacles.〔 The internal gastric cavity is connected to a network of canals forming a meshwork in the mesoglea. 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「Beroe ovata」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
