Review by Meredith MacKeen. Crabtree Publishing, 2000. Review by Meredith MacKeen. A mammal is an animal that drinks milk from its mother's body as a baby. All mammals are warm blooded, which means their body temperature stays the same in warm or cold places.
Most mammals have some hair or fur on their body.
About 4600 species, or types of mammals live on Earth. Each is successful in appealing to students in the grade 3 to 6 range and in providing appropriate information. The books each begin with a definition of the type of animal being examined and continue through a review of related orders, characteristics, body features, mating and parenting, food, homes, and relationship to the environment, including human beings. Two page spreads cover special examples of the mammal or amphibian written up. Specific information is easily located via the explicit headings in the table of contents and a glossary is provided.
