Description
The Japanese fire-bellied newt or Japanese fire-bellied salamander is a species of newt endemic to Japan. The skin on its upper body is dark and its lower regions bright red, although coloration varies with age, genetics, and region. Adults are 8 to 15 cm long. To deter predators, Japanese fire-bellied newts contain high levels of tetrodotoxin, a neurotoxin accumulated mainly from their diet.
