The term Amphibian can be interpreted in two ways, either as an animal spending part of its life in water and then changing to an aquatic adult, or as an animal spending its life in and out of water. Amphibians are surprisingly variable. They are caecilians, salamanders, and anurans. They normally live in burrows of tropical regions. All salamanders have scaleless skin, four legs and a tail.
Anurans are either frogs or toads.
They normally move around in hops. Many amphibians metamorphose, or change, from a gill breathing aquatic larvae to an air breathing terrestrial adults. These amphibians have great abilities. A new born tadpole carries an aquatic life. After it metamorphoses, it becomes terrestrial.
