At the Central Florida Zoo, you can see a variety of amphibians in our Herpetarium, including poison dart frogs, salamanders, and the African bullfrog. We also house amphibians in our Insect Zoo. Classified by their wet skin, amphibians must remain near water or in damp areas to prevent their extremely porous skin from drying out. Many amphibians actually breathe and absorb water through their skin, so amphibians serve an important role in indicating if a water system is healthy or not. Amphibians also secrete a mucous coating to keep from drying out. For most amphibians, this secretion is actually poisonous to predators and serves as protection as well.
