In this video segment from WILD TV, learn about the Florida Everglades, a giant wetland that is the habitat of many different species of animals. One of the animals featured in the video is the pig frog, named for the sound they make which is similar to a pig’s grunt. They contribute substantially to the ecosystem of the Everglades. Their permeable skin helps reflect toxins in the ecosystem. Scientists are studying pig frogs because they believe the frogs act as indicators of the health of the Everglades. They are an important part of the food chain that affects animals both far and near.
