The remarkable adaptations of turtles, tortoises and terrapins have helped them survive for over 200 million years. They are the most wide-ranging of reptiles, found in deserts, forests and the open ocean. But they are also among the world's most endangered animals. They face the multiple threats of habitat destruction, poaching, overhunting (for food and traditional medicines), deadly tangles with fishing lines and capture for the international pet trade. Around the world, turtle populations are under attack on land and sea. Many species are close to extinction and efforts are underway to save them. It is among the main goals of this book to foster awareness about these unique and threatened creatures. In this new edition, zoologist Ronald Orenstein describes the astonishing ways that turtles cope with their environment. He updates readers on the latest discoveries and explores the debate on origins of the turtle. Every aspect of their evolution, life history and conservation status is presented in 250 photographs and lively text supplemented with numerous maps and a bibliography. The battle to save turtles goes on. Turtles, Tortoises and Terrapins is fascinating, informative and essential for anyone interested in these amazing creatures and concerned about their precarious future.
