In some parts of the world, the arrival of spring is announced by the guttural chorus of tree frogs. As their name suggests, these frogs spend most of their lives in trees. They tend to be small and slender since their weight must be supported by branches and twigs in their habitats. They can be recognised by the sticky discs on the tips of their fingers and toes, which help them cling to surfaces. There are over 8,000 species of tree frogs, typically found in Central America, Europe and Australia. The American green tree frog is the official state amphibian of both Louisiana and Georgia. A fascinating fact about frogs is that they have three eyelids; the third helps them hide, hibernate and sleep.
