The stolon meanders along the surface of the substrate forming a mat. The base of each zooid is attached to the stolon and its body resembles a small barrel, with an opening at the top and another at the side, each opening raised on a rim. These are the buccal siphon through which water flows into the body of the animal and the atrial siphon through which it is expelled. A large pharynx occupies much of the interior and the surrounding muscular body wall is known as the mantle. The pharynx opens into a horizontally aligned gut which loops around to terminate near the atrial siphon. There are four bands of "stigmata" on the inside of the mantle, a fact that this species has in common with ''Perophora regina'' but which distinguishes it from several other western Atlantic members of the genus ''Perophora'' which have five bands.〔 The outer surface of the zooid is known as a tunic and is gelatinous and translucent. It is colourless but the animal appears green because of the blood corpuscles circulating in blood vessels within the mantle. The arrangement of muscles in the mantle is important for distinguishing ''Perophora viridis'' from other species. These muscles are limited to about twelve muscles running longitudinally from the siphonal plate, a slightly depressed area between the siphons. The muscles extend for about a quarter of the length of the zooid and their function is to enable the animal to contract and protect its siphons. The only other musculature is the circular sphincter muscles which control the size of the siphons. The siphons each have six or more pointed lobes and the opening into the pharynx is surrounded by ten large and ten small tentacles, designed to prevent the entry of particle too large for the animal to cope with. The pharynx occupies most of the body cavity and is surrounded by a water-filled atrium. This is criss-crossed by various mesenteries which provide support for the pharynx and the rest of the gut.〔 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「Perophora viridis」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.
