Vertebrates include fish, amphibians, reptiles, birds, and mammals. Analyze the common characteristics if reptiles and explain how they are different from mammals. Explain in two sentences.
Reptiles are cold-blooded animals that have scales, lay eggs, and typically have a dry, scaly skin. Unlike mammals, reptiles do not have mammary glands or give live birth, and they rely on external sources of heat to regulate their body temperature, rather than producing their own body heat.
