The fire-bellied toads or firebelly toads are a group of eight species of small frogs (most species typically no longer than ) belonging to the genus ''Bombina''. "Fire-bellied" is derived from the brightly coloured red- or yellow-and-black patterns on the toads' ventral regions, which act as aposematic coloration, a warning to predators of the toads' reputedly foul taste. The other parts of the toads' skins are green or dark brown. When confronted with a potential predator, these toads commonly engage in an Unkenreflex, "Unken-" being the combining form of "Unke", German for fire-bellied toad. In the Unkenreflex, the toad arches its back, raising its front and back legs to display the aposematic coloration of its ventral side. == Species == The currently recognized species are:〔(''Bombina'' ), Amphibian Species of the World 5.6〕 * ''B. bombina'' – European fire-bellied toad * ''B. lichuanensis'' – Lichuan bell toad * ''B. fortinuptialis'' – large-spined bell toad or Guangxi firebelly toad * ''B. microdeladigitora'' – Hubei firebelly toad, considered a synonym of ''B. maxima'' * ''B. maxima'' – Yunnan firebelly toad * ''B. orientalis'' – Oriental fire-bellied toad * ''B. pachypus'' – Apennine yellow-bellied toad * ''B. variegata'' – yellow-bellied toad 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「Fire-bellied toad」の詳細全文を読む スポンサード リンク
