This primeval amphibian can grow up to five feet long and weigh over 50 pounds, making it one of the largest salamanders to ever crawl the face of the Earth. Despite it's primitive look, the Japanese giant salamander is highly evolved. It is covered head to tail with specialized cells that detect tiny vibrations in its environment. When it detects a threat, it excretes a strong-smelling ooze that smells like a Japanese pepper, hence, its common Japanese name, giant pepper fish. The Japanese giant salamander is entirely aquatic, and spends its life in clear, cool flowing streams. It has no gills, but instead absorbs oxygen through its skin. If left alone, the Japanese giant salamander will live a long life. This one is 26 years old, and in the wild they can live to be nearly 80. But pollution of its river habitat, and over collection, are threatening this fascinating primordial creature. This is the Japanese giant salamander. (restless music)
