Frogs and toads are often confused with each other. Toads usually have shorter legs than frogs. So, where frogs leap, toads simply hop. Also, toads don't live as close to water as most frogs do. Toads have thicker skin than frogs and can live in drier environments.
Salamanders are the second major type of amphibian.
They usually have long, lizard-like bodies and most have two or four legs. They are very much like frogs because they spend their lives in the water or wet environments. To live in water, salamanders need gills. Some salamanders are aquatic and never lose their gills, but some adult salamanders lose their gills and live on land. Reptiles Reptiles vary in size from very small to very large, and they have scaly skin.
