AmphibiansAmphibians are cold blooded, breathe air through their skin and do not have hair or scales. Amphibians go through a metamorphosis; starting from an egg, morphing into larvae that is typically aquatic, breathing by gills, and growing into semi-terrestrial adults that breathe by lungs and through moist skin.
Reptile Or Amphibian?Amphibious means ‘belonging to both land and water’ - but not all amphibious creatures are amphibians. Marine iguanas, sea snakes, crocodiles and pond turtles are all amphibious but they are considered reptiles because they do not go through a metamorphosis. They also have scales; amphibians have no scales. While both amphibians and reptiles come from eggs, amphibian eggs need to stay moist or wet as they develop and are usually laid in water.
