This is a picture of a baby lizard. Lizards are ectotherms, meaning they are dependent on external sources of body heat, such as sunlight or a heated rock. Ectotherms are called cold-blooded animals. They include fish, amphibians, reptiles, and invertebrates. Ectotherms are also different from endotherms in that they require less food for animals of the same size, however they cannot deal as well in cold environments.
