Amphibians

Amphibians are animals that live part of their lives in water and part on land. They are vertebrates and ectothermic; they cannot regulate their own body heat, so they depend on sunlight to become warm and active. Amphibians also can’t cool down on their own, so if they get too hot, they have to find a burrow or some other shade. In cold weather, amphibians tend to be sluggish and do not move around much.
