What is a Frog?

Frogs are a kind of small animal belonging to a group called vertebrates (animals with backbones) known as amphibians. This mean that they live part of their life in water and the other part of it on land. The word amphibian comes from 2 Greek words, "amphi" which means "both" and "bios" which means "life". Amphibians are cold-blooded animals. This mean that their body temperature is the same as the surrounding temperature. Their skin absorbs water into their body so they do not have to drink water to survive. Frogs have strong hind legs to enable them leap forward at a great distance. The front legs or arms are short. They are used to prop the frog up when it sits.
