There are over 6,400 species of amphibians found worldwide, except in Antarctica and Greenland. Amphibians are vertebrates and include animals such as frogs, toads, salamanders, newts and worm-like caecilians. They can be found on land, and in fresh water. They live in a variety of habitats from deserts to rain forests, permanent ponds or high mountain meadows. Most amphibians have four limbs, but some amphibians don't have any limbs. Amphibians are cold-blooded meaning they use the environment to regulate their body temperature. Amphibians spend part of their life in water, and part of their life on land.
