Children's LiteratureThe format of the book consists entirely of numbered one or two sentence facts about polar bears and their behavior. For example, "The polar bear is the biggest four-legged carnivore on Earth." Although this may seem like a disjointed approach, the facts actually are organized logically (facts about polar bears' hunting techniques are grouped together, for example). Breaking the facts down into labeled sections or chapters would have been even more helpful, however. Instead, young researchers must either read the book cover to cover or else rely on the brief index. Color photographs appear on almost every page, including action pictures of polar bears swimming, fighting, and jumping. A color-coded opening map indicates the arctic zones where polar bears live, and a glossary defines key boldfaced terms. A guide for further reading and a list of web sites will lead readers to other more in-depth resources. This is a volume in the "101 Facts About Predators" series. 2004, Gareth Stevens Publishing, Ages 7 to 12.
