define amphibian ?

Amphibians are four-limbed, ectothermic animals that belong to the class Amphibia. The phylum Lissamphibia includes every extant amphibian. They live in a broad range of habitats, with the majority of species being found in freshwater aquatic, terrestrial, fossorial, or arboreal settings. Therefore, amphibians normally begin their lives as aquatic larvae, but certain species have evolved behavioural adaptations to get around this.

The young typically transition from a larval stage with gills to an adult form with lungs. Some tiny terrestrial salamanders and frogs rely solely on their skin for respiration, whereas amphibians use their skin as a supplementary respiratory surface. Although they resemble lizards on the surface, reptiles, like mammals and birds, are amniotes and do not need bodies of water to survive.
