In 2014 a giant salamander emerged from the Kamo River in Japan. Landed appearances of the giant creature are considerably rare due to them making their home underwater and being only active at night. Japanese giant salamanders are the second-largest salamanders on Earth, surpassed only by the closely related Chinese giant salamander. They feed on insects, frogs, crabs, shrimp, and fish; but since the 1950s, their population has declined rapidly due to habitat destruction and overhunting.
The Chinese giant salamander (Andrias davidianus) is the largest salamander and largest amphibian in the world, reaching a length of 180 cm (6 ft), although it rarely – if ever – reaches that size today. It is endemic to rocky, mountain streams and lakes in China, as well as Taiwan, probably as a result of introduction.
The Chinese Giant Salamander is the world’s largest amphibian, growing to lengths of up to 6 feet. It used to be common throughout central, southwestern and southern China, where it lives in streams in the forested hills and lays up to 500 eggs at a time in underwater burrows guarded by the male. However, the Chinese giant salamander has now almost completely disappeared due to its over-exploitation as a food source.
