| Mammals | ||
| One class of vertebrates is the mammals. All mammals share several characteristics. They breathe air with lungs and make milk for their young. Most mammals have hair or fur. Mammals are warm-blooded. That means they keep their body temperature nearly the same all the time. Young mammals are usually born looking very much like their parents. |

| All life continues through different life cycles. A life cycle is a pattern of birth, growth, reproduction, and death. As they grow, animals develop and then reproduce. At the end of their life cycle, animals die. Their offspring repeat the cycle. |
