Japanese Giant Salamander
Range and habitat:
Size / weight range:
Unlike most salamanders that have internal fertilization, the giant salamanders have external fertilization and spawn. Males prepare a den in a stream and entice females to enter and lay their eggs.
The folds of
skin on sides of these animals help it to obtain oxygen with the rapid
moving water in streams. The giant salamanders prefer cold water, which
has a higher oxygen content than warm water. These salamanders have lived
for 55 years in zoo settings, but their maximum longevity has been estimated
to be closer to 100 years.
