The Central Coast stubfoot toad, ''Atelopus franciscus'', is a species of toad in the Bufonidae family, endemic to the central coastal region of French Guiana. It is a locally common, diurnal species found near fast-flowing small streams and creeks in lowland rainforest.〔〔 Many authors have suggested this taxon might be a synonym of ''Atelopus flavescens''.〔 It is threatened by habitat loss ==Reproduction and behaviour== To attract females and to defend their territories, males of ''A. franciscus'' use advertisement calls, not visual displays as typical for ''Atelopus''. This is somewhat unexpected, given their environment is noisy and males must acoustically compete with males of several other frog species (e.g., ''Allobates femoralis'' and ''Otophryne pyburni''). Moreover, this species lacks an external vocal sac, so can only produce low-intensity calls that propagate short distances (<8 m). It also lacks external tympana and could be considered anatomically deaf. Nevertheless, it has a well-developed inner ear and has been shown to respond acoustically to the calls of conspecifics in the field.〔 Male territories are closely spaced, only 2–4 m apart on average, and despite the handicaps discussed above, acoustic communication appears sufficiently efficient at these short distances. Eggs are laid in the water. The tadpoles adhere to rocks.〔 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「Central Coast stubfoot toad」の詳細全文を読む スポンサード リンク
