The Double-crested Toad is an amphibian with two high bony crests on the head. It lives in tropical forests of Southeast Asia, hunts insects, and returns to water only to lay eggs.
The Double-crested Toad differs from related species by two sharp crests on the head that protect the eyes. It is important for the forest because it eats many insects and becomes food for snakes and birds.
Immature form that undergoes metamorphosis before adulthood.
