According to the San Diego Zoo, toads are amphibians. The National Wildlife Federation indicates that the life cycle of amphibians involves time on land and in the water. They have gills during some or all of their lives, while reptiles always breathe with lungs. Reptiles, not amphibians, have scales.
Toads are sometimes confused with another kind of amphibian: frogs. The zoo states that the body of a toad is thicker than a frog's, and a toad's legs are shorter. Toads tend to have dry and bumpy skin, while frog skin is smoother and moist. Frogs usually live in or near water, while toads generally stay on land. While these characteristics are typical of these amphibians and often help tell them apart, there are exceptions.
