''Herpetology, Fourth Edition: An Introductory Biology of Amphibians and Reptiles'', p. 453. ISBN 978-0-12-386919-7〕 They are viviparous animals, giving birth to young that possess external gills. Of the five genera in the family, ''Atretochoana'', ''Potomotyphlus'' and ''Typhlonectes'' are entirely aquatic, while ''Chthonerpeton'' and ''Nectocaecilia'' are semi-aquatic.〔 ''Atretochoana'' reaches in length, but other species in the family range from .〔 ==Taxonomy== *Genus ''Atretochoana'' * *''A. eiselti'' *Genus ''Chthonerpeton'' * *''C. arii'' * *''C. braestrupi'' * *''C. exile'' * *''C. indistinctum'' * *''C. noctinectes'' * *''C. onorei'' * *''C. perissodus'' * *''C. viviparum'' *Genus ''Nectocaecilia'' * *''N. petersii'' *Genus ''Potomotyphlus'' * *''P. kaupii'' *Genus ''Typhlonectes'' * *''T. compressicauda'' - Cayenne caecilian * *''Typhlonectes natans'' 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「Typhlonectidae」の詳細全文を読む スポンサード リンク
