Amphibians Amphibians are usually small animals that live in damp environments like swamps and ponds. They go through different stages of development from egg to tadpole and finally, to the adult. This process is called metamorphosis. The egg and tadpole stages require water, while adults may be terrestrial or aquatic. 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.
