Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia.
They inhabit a wide variety of habitats with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems.
Amphibians are cold-blooded vertebrates that do not maintain their body temperature through internal physiological processes.
Their metabolic rate is low and as a result, their food and energy requirements are limited.
In the adult state, they have tear ducts and movable eyelids, and most species have ears that can detect airborne or ground vibrations.
They have muscular tongues, which in many species can be protruded.
