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 in the world, and is fully aquatic, with many adaptations for this lifestyle. It grows up to 1.8 metres in length, though most individuals found today are considerably smaller
