List of reptiles and amphibians of Alaska

From Wikipedia, the free encyclopedia

Alaska is the northwestern most part of North America. Reptiles and amphibians are not common in Alaska due to them being cold-blooded. Alaska has four reptile species and eight amphibian species. Two of these species are introduced species. There are no snakes or lizards in Alaska.[1]
