Sharks by Penny Clarke
With informative captions, a glossary and an index, Sharks is full of facts written in an accessible question-and-answer format. The x-ray style format of some of the pages enables readers to see how the internal structure of sharks corresponds to their external appearance, and how a shark's skeletons and muscles work. This book also describes the processes of nutrition, growth and movement in sharks, and indicates links between animals and their environments.
