This informative book focuses on the similarities and differences between "familiar animal look-alikes" such as the alligator and the crocodile, the tortoise and the turtle, and the camel and the dromedary. For each of seven look-alike pairs the straightforward text compares such attributes as physical appearance, physiology and anatomy, history, diet, life span, gestation, and the rearing of young. The relationship to humankind is also covered; for instance, bison and buffalo have almost been exterminated because of westward expansion in North America. Dramatic cross-hatched drawings open each chapter, and similar, black-line illustrations enhance the text. A glossary lists common and scientific names for more than 50 species. The inherently appealing topic guarantees an audience. Bibliography.
