Perceived as predatory killers, crocodilians face extinction because of little human sympathy. Yet these fine hunters, with their tough skin, almost fully submerged bodies, and keen eyes that see in the dark and judge distance precisely, have the power to fascinate. Investigate their origins, evolution, and distribution, courtship, reproduction, and the various species. Maps of their rapidly disappearing habitats and excellent color photos bring these sometimes-scary reptiles up close and personal. 192 pages, 40 color illus., 80 b/w illus., 6 x 9.
