Depending on your location, seeing a salamander is not particularly out of the ordinary. If you are exploring the brooks and ponds of China or Japan you may come across a Salamander so large that you may mistake it for some sort of river monster. The Chinese (Andrias davidianus) and Japanese (Andrias japonicus) giant Salamanders can grow up to 6 feet in length or larger dwarfing the next largest Salamander species, the American Hellbender (Cryptobranchus alleganiensis), which only reaches lengths of just over 2 feet.

The Japanese variety is the smaller of the two growing to only 4 feet 9 inches. It is entirely aquatic, living is the clear cool streams of Japan. Hunting at night and having very poor eyesight, the Japanese Giant Salamander depends on special sensory nodes in its forehead to detect its prey’s movement through the water.
