Frogs and Toads of Florida Frogs and Toads of Florida 1 Joe Schaefer and Jennifer Liebertz 2 Frogs and toads are members of the class Amphibia, the first backboned animals to live on land. Most toads, except the eastern narrowmouth toad, have dry, warty skin, whereas frogs have moist, smooth skin.
Most toads also have a pair of parotid glands bulging out from behind their eyes.
These glands produce a bufotoxin that protects them from being eaten by most animals. All toads have these glands, but most are too small to severely affect people and our pets. Frogs do not possess these glands, and there are no poisonous frogs in Florida. Frogs and toads have evolved characteristics that allow them to survive on land. Adult frogs and toads have a keen sense of smell.
