Did you know that you can find frogs on every continent except Antarctica? In Frogs for Kids, you'll learn lots of cool facts. For instance, true frogs include the bullfrog, common frog, green frog, leopard frog, marsh frog, pickerel frog, and wood frog. They are called "true frogs" because of their body form and history. Part of their life cycle is spent in the water (aquatic), and part is spent on land (terrestrial). You may have seen the bullfrog or common frog in streams, ponds, or marshes near your home! Frogs can be shy, though. When you approach them, they leap for cover, preferably in water.

Perhaps you have heard of or seen tree frogs! Tree frogs are fascinating. They have special adhesive pads and claws on their feet to help them climb. Though most are small, some species can grow nearly six inches long. Tree frogs come in various colors. Their bright coloring serves two purposes. One is to camouflage them from predators. The other, for some species, is to alert predators that the frog is poisonous. Similarly, dart frogs also have very vibrant coloring, and some species are poisonous as well. In fact, the poison dart frog produces enough toxins to be deadly to humans. It is considered one of Earth's most toxic, or poisonous, animals.

There are several reasons why frogs are essential to the environment. Frogs eat disease-carrying mosquitoes and are a vital food source for hundreds of animal species. Tadpoles feed on algae, which keeps streams and ponds clear. And frogs are known as bioindicators. Bioindicators are sources that indicate how healthy an ecosystem is. Remember that frogs absorb water through their skin; toxins such as pollution from factories come with the water. Scientists can measure how much of a toxin a frog absorbs and estimate how unhealthy the water is. Healthy frogs are one indicator of a healthy biosystem. Scientists also use frogs in medical research.
