Andrias japonicus

100-144 cm long, Andrias japonicus is passed as size, in the Caudata order, only by the analogous Andrias davidianus. It spends the whole life in water and is endemic to the streams of Kyushu island in Japan. It stays hidden in a den during the day and gets out by night hunting fishes, amphibians and crustaceans. The reproduction occurs in summer with tadpoles that take 3 years to metamorphosize. Captive, it may pass the 50 years © G. Mazza
