Sharks have been greatly maligned in literature and film. Levine offers readers information about great white sharks-their incredible bodies are streamlined for speed in the ocean and their teeth are serrated and constantly replaced. Readers learn about the shark's ancestors, and the special adaptations relating to metabolism, fins, liver and their senses including special nerves that let them detect weak electrical fields. Once kids start reading about these creatures, they will not want to put the book down. Photographs and illustrations fill the pages. The book concludes with twenty fascinating facts about the great white shark, a glossary, suggested reading list and an index. Part of "The Untamed World" series, Levine's book is a good selection for kids who want more than introductory information.
