| | Reptiles differ from other terrestrial vertebrates (birds and mammals) in that they are cold-blooded, that is, they lack an effective system for regulating their body temperature, which tends to approach that of the environment. | | | Most mammals have highly evolved sense organs and larger brains than other vertebrates. | | | Like the birds, they have a four-chambered heart and a double-circuit circulatory system and are able to regulate body temperature. |
