Vertebrae include fish, amphibians, reptiles birds and mammals, analyze the common characteristics of reptiles and explain how they differ from mammals. Explain your answer in one or two sentences.
Reptiles and mammals are both vertebrates, but reptiles are ectothermic (meaning they rely on external sources of heat to regulate their body temperature) and typically have scales, while mammals are endothermic (meaning they can regulate their body temperature internally) and have hair or fur. This difference in temperature regulation and skin covering are key distinguishing characteristics between reptiles and mammals.
