This informative title begins by explaining how living things fit and adapt to their environments, and how this helps creatures survive and thrive. The text then gives examples of different forms of adaptations, such as body temperature regulation, defense mechanisms, and movement variations. Two case studies highlight specific animals and their survival skills. The many captioned color photographs complement the text, while numerous sidebars and diagrams deliver additional facts. The “Timeline of Prehistoric Adaptations,” suggested reading, Web sites, and DVDs, and “Topics to research” will be particularly helpful to report writers. A glossary and an index round out the back matter.
