The average life expectancy of tree frogs varies in different species. Some of them live quite a while, although there are fewer toads. For example, the Australian Green Tree Frog often lives up to 15 years or more in captivity. Species with a life expectancy of less than three years are considered short-lived. The gray tree frogs of North America occupy an intermediate position with a life expectancy of five to nine years.
Not surprisingly, the vast majority of tree frogs live on trees. They have special tools for this: discs at the fingertips and long legs for jumping. But not all species prefer trees. Among the woods there are frogs that live in lakes and ponds, as well as in wet forest litter.
Although tree frogs are found on every continent (with the exception of Antarctica), they are most widely represented in the tropics of the New World. About 30 species live in the United States, and more than 600 can be found in South and Central America.
