''Chelidonura hirundinina'' is a species of small and colorful aglajid sea slug, a shell-less opisthobranch gastropod mollusk in the family Aglajidae.〔Rosenberg, G. (2011). Chelidonura hirundinina (Quoy & Gaimard, 1833). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=420528 on 2012-05-17〕 The variety ''Chelidonura hirundinina'' var. ''punctata'' Eliot, 1903 has been elevated to the species ''Chelidonura punctata'' Eliot, 1903 Despite its colorful appearance, this is not a species of nudibranch; it is a cephalaspidean, a headshield slug. This is a tropical species which lives in the western Indo-Pacific, and also in the Caribbean Sea. ==Description== This species has a maximum size of 40 mm, but is often smaller than that. The background color can be red, orange, dark brown, or black. There are blue, black, and orange stripes on the body, and there is a white marking towards the posterior end of the animal. The two rather long "tails" at the end of the animal are characteristic of the genus ''Chelidonura''. They have also well-developed sensory cilia on the anterior edge of the head which are used to find the prey. The specific epithet ''hirundinina'' is Latin, meaning "little swallow", in reference to this swallow-tailed appearance. 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「Chelidonura hirundinina」の詳細全文を読む スポンサード リンク
