Summary[edit]

Description
Русский: Ареал - Центральная и Восточная Европа (до Урала), в Западной Европе популяция значительно снижена. В случае опасности на суше жерлянки подворачивают на изогнутую спину лапы, демонстрируя ярко окрашенную нижнюю часть тела, предупреждая о своей ядовитости. Это оборонительное поведение называют «рефлексом жерлянки», хотя встречается оно и у других бесхвостых амфибий. Жерлянки не ядовиты для человека, хотя в их коже содержатся бактерицидные пептиды. Срок жизни обычно около 15 лет.
English: The distribution area is concentrated in Eastern and Central Europe; North-West, it ranges up to southern Sweden, Denmark, in the South to Bulgaria.

"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.

If attacked by a vertebrate on land the European fire-bellied toad makes a hollow-back and lifts its four legs so that the ventral warning colour is displayed. The combination of dark and red is a learned signal meaning “attention poison” to the enemy.
