M., Stöger I., Kano Y., Fukuda H., Knebelsberger T. & Schrödl M. (2010). "On the origin of Acochlidia and other enigmatic euthyneuran gastropods, with implications for the systematics of Heterobranchia". ''BMC Evolutionary Biology'' 10: 323. .〕 Bubble shells is another common name for these families of marine gastropods, some of which have thin bubble-like shells.〔Dance S. P. (1996). ''Shells. The visual guide to over 500 species of seashell from around the world''. Dorling Kindersley. London, New York, Stuttgart.256 pp. pages 200-203. ISBN 0-86318-811-7.〕 Members of this worldwide clade appear to be the most primitive of the opisthobranchs. Headshield slugs are the most morphologically diverse group of all the opisthobranchs. ==Anatomy== The vast majority possess a shell, although it may be reduced or internal. They have a well-developed headshield, a characteristic broadening at the head, which is used to plow beneath the surface of the sand. This headshield prevents the sand entering the mantle cavity. There is a muscular foot with or without parapodia (fleshy wing-like flaps). 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「Cephalaspidea」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.
