Frogs belong to a group of animals called amphibians. Amphibian means two-lives. Frogs begin their lives in the water as eggs and then tadpoles and when they are fully developed they live on land. Scientists believe that there are more than 4,000 different kinds of amphibians on Earth. Toads, newts, salamanders and caecilians blind worms are also members of the amphibian group. Frogs are cold-blooded which means that their bodies are the same temperature as the air or water around them. When they are cold they will lay in the sun to warm up and when they get too warm they will go into the water to cool their bodies off.
