Amphibians & Reptiles

Antarctica is the only continent that has no native amphibian species. Amphibians and reptiles are very important vertebrates on the Pacific Islands. Surprisingly, given their importance, there are only six reptiles native to the Hawaiian Islands and all of them live in the sea. The rest of Hawaii's reptiles and amphibians are invaders.
