It is a cylindrical, unsegmented worm with a crown of tentacles around the mouth. It lives in burrows in shallow seas in various parts of the world. ==Description== Like other sipunculans, the body is divided into a larger rear end known as the trunk and a narrower front end known as the introvert. The trunk is cylindrical and can reach 200 mm in length but is more commonly 20-50 mm.〔Cutler, Edward B. (1994) ''The Sipuncula: their Systematics, Biology, and Evolution'', Cornell University Press, Ithaca, New York.〕 It varies in colour from grey to white to yellow-brown.〔Barnes, M.K.S. (2008) (''Golfingia vulgaris''. A sipunculid worm. ) Marine Life Information Network: Biology and Sensitivity Key Information Sub-programme, Plymouth: Marine Biological Association of the United Kingdom. Accessed 29 March 2009.〕 The two ends of the trunk are often pigmented dark brown or black. The introvert can be retracted into the trunk by the retractor muscles of which there are usually four but occasionally three.〔 The introvert bears many dark brown, slightly bent hooks. These are arranged irregularly unlike the similar species ''Golfingia elongata'' where the hooks are arranged in rings.〔Fish, Susan (2006) ''A Student's Guide to the Seashore'', Cambridge University Press.〕 Young specimens have a crown of around 20 small, finger-like tentacles arranged in a circle around the mouth. As the worm grows the number of tentacles can increase to over 150 and they are arranged in three or more circles.〔de Kluijver, Mario & Sarita Ingalsuo. ''(Golfingia vulgaris ), (Marine Species Identification Portal ). Accessed 29 March 2009.〕 The entoproct ''Loxosomella phascolosomata'' often attaches itself to the worm.〔 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「Golfingia vulgaris」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.
