Japanese Giant Salamander (Andrias japonicus)

The Japanese Giant Salamander lives in Japan's mountainous landscapes. Its crinkled and coarse skin helps it blend in with the rocks in its watery habitat. Like other salamanders in the Andrias genus, it is large, reaching up to 5 feet.

These types of salamanders are nocturnal creatures that rely on their sense of smell and touch to hunt for fish, insects, worms, and small mammals. During the breeding season, males become aggressive and fiercely guard their nesting sites, which can hold up to 500 eggs.
