翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Cream-backed poison frog ： ウィキペディア英語版 Cream-backed poison frog ''Hyloxalus subpunctatus'', also known as the cream-backed poison frog, is a species of frog in the Dendrobatidae family. It is endemic to Colombia. Its natural habitats are subtropical or tropical high-altitude grassland, shrub-dominated wetlands, swamps, intermittent freshwater marshes, rural gardens, urban areas, and heavily degraded former forest. The cream-backed poison frog is one of the less-toxic of the family. It has undergone several name changes since its discovery. Originally called ''Dendrobates subpunctatus'', its name was changed to ''Colostethus subpuctatus'' once the family Dendrobatidae underwent a division of species and genera other than ''Dendrobates'' were coined. Recently, minor skeletal differences has separated the cream-backed poison frog from the rocket frogs, and placced it in another genus entirely, ''Hyloxalus''. == Toxin == Like many of the ''Hyloxalus'' genus, ''H. subpunctatus'' possesses fairly weak toxins, compared to those of other dendrobatids. It may be one of the most primitive of dendrobatids, as it has only begun to develop skin alkaloids and is still fairly drab in coloration. Its poison is already an effective defense mechanism: if tasted by a predator, the alkaloids in the frog's skin cause extreme pain and unpleasant taste. This will usually discourage a predator from attacking a cream-backed poison frog more than once. However, ''H. subpunctatus'' is still vulnerable to more determined predators, such as snakes, which is further evidence that it may be a fairly young species compared to other inedible or even deadly dendrobatids. 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「Cream-backed poison frog」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.
