Unique, unusual behaviors such as those of the poison arrow frogs described on the previous page are much more likely to occur in the tropics. In the temperate zone, most frogs behave in very similar and more predictable ways. In the tropics, however, there are not only more varied habitats and more opportunities for specialized behavior, there are also more frogs. The entire United States is home to only 80 species of frogs, while Ecuador, a South American country smaller than the state of Nevada, has over 300 frog species.

Many frogs live near shallow wetlands, which are perfect tadpole habitat. Photo by Maya Walters.
