The Japanese giant salamander is a bit smaller than its Chinese counterpart, while North America’s largest salamander, the hellbender, may reach 28 inches (70 centimeters) in length. The Japanese giant salamander is restricted to streams with clear, cool water. This scaly skin is what enables lizards to live in some of the harshest and driest areas in the world. These notable behaviors included the male’s fanning the nest with his tail—likely to oxygenate the nest—and also vigorously “agitating” the eggs, which is theorized to assist with embryonic development. The hellbender is a large salamander found in fast-flowing rivers and streams in the eastern United States. Physical Characteristics Skin Lizard.
