The Bombinatoridae are often referred to as fire-bellied toads because of their brightly colored ventral sides, which show they are highly toxic. This family includes two genera, ''Barbourula'' and ''Bombina'', both of which have flattened bodies. ''Bombina'' species are warty, aquatic toads about in length, and most noted for their bright bellies. They often display the unken reflex when disturbed; the animal will arch its back and limbs to expose the bright belly, and may turn over on its back. This acts as a warning to predators. The vocal behavior of some ''Bombina'' sp. is unusual in that the call is produced during inhalation rather than exhalation as in other frogs. They lay pigmented eggs in ponds. ''Barbourula'' species occur in the Philippine Islands and Borneo, while ''Bombina'' species are found throughout Eurasia. They are slightly less colored than ''Bombina'', and possess webbed fingers in addition to webbed toes. Characteristics of tadpoles of ''Barbourula'' are unknown. ''Barbourula'' was considered to be situated intermediate between ''Discoglossus'' and ''Bombina'', but closer to the latter, and was therefore also added to the Bombinatoridae when that family was split from the Discoglossidae. Fossil ''Bombina'' specimens are known from the Pliocene to the Pleistocene; there are no known fossils of ''Barbourula''. ==Species== Family BOMBINATORIDAE * Genus ''Barbourula'' * * ''B. busuangensis'' - Philippine flat-headed frog or Busuanga jungle toad * * ''B. kalimantanensis'' - Bornean flat-headed frog or Kalimantan jungle toad * Genus ''Bombina'' * * ''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「Bombinatoridae」の詳細全文を読む スポンサード リンク
