Amphibians are cold-blooded (ectothermic) vertebrates. Their body temperature stays at or near the temperature of the ground or air. All the amphibian species you will learn about here, will grow from an egg to a juvenile while underwater. While they are in that aquatic form, they have no lungs; they must get oxygen from the water. When they change form (metamorphose) into an adult, they acquire lungs that can get oxygen from the air.
