What is a amthibian?

An amphibian is a cold-blooded vertebrate animal that typically begins its life in water, undergoing metamorphosis to develop into a terrestrial adult. This class includes frogs, toads, salamanders, and newts. Amphibians are characterized by their moist skin, which aids in respiration, and they often require a humid environment to survive. They play crucial roles in ecosystems as both predators and prey.
