翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Gyraulus ： ウィキペディア英語版 Gyraulus ''Gyraulus'' is a genus of small, mostly air-breathing, freshwater snails, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails.〔Ivanov M., Hrdličková, S. & Gregorová, R. (2001) Encyklopedie zkamenělin. – Rebo Productions, Dobřejovice, 1. vydání, 312 pp., page 126. (in Czech)〕 The genus ''Gyraulus'' is known from the Early Cretaceous to the present. Fossils attributed to ''Gyraulus'' sp. have been found in the lakebottom sediments of the Yixian Formation in China, dating to 125 million years ago.〔Pan, H. and Zhu, X. (2007). "Early Cretaceous non-marine gastropods from the Xiazhuang Formation in North China." ''Cretaceous Research'', 28(2): 215-224. 〕 The minute species ''Gyraulus crista'', although technically a pulmonate gastropod, does not use air for respiration, but instead has a mantle cavity which is full of water. ==Distribution== The distribution of this genus is Holarctic. 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「Gyraulus」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.
