Comprehensive coverage ... their evolution, life history and conservation.

Nature Magazine
With deft prose and engaging anecdotes, Mr. Orenstein takes us skillfully through a vast amount of information....[his] treatment is nothing short of masterly.

Abounds with excellent color photographs. Recommended for all public and academic libraries.

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.

PREFACE: Why Turtles Matter

"Turtles," Anders Rhodin of the Chelonian Research Foundation wrote over ten years ago, "are in terrible trouble." I began the preface to the first edition of this book with his words. For the second edition I can do no better than quote him again, this time from a statement he made in 2011: "Turtles are in serious trouble. They are some of the world's most endangered vertebrates, more than mammals, birds, or even highly endangered amphibians."

Few herpetologists--the scientists who study reptiles and amphibians--would disagree with him. His 2011 statement was made upon the release of a multi-authored report, Turtles in Trouble: The World's 25+ Most Endangered Tortoises and Freshwater Turtles--2011, detailing just how bad things are. Half of the turtle species in the world are threatened with extinction. There is hardly a place left on earth, land or sea where turtles are safe. In some places, most particularly in southern Asia where forests and rivers are being swept clean of turtles to supply growing and voracious markets for food and pets, their situation is little short of desperate. Some species have probably already disappeared; more will almost certainly do so, or be reduced to an existence in captive colonies, despite efforts we make to save them. Pollution, habitat destruction, overhunting, climate change and disease strike at species after species. During the last five years of the 20th century, populations of the largest turtle in the world, the Leatherback Sea Turtle (Dermochelys coriacea), collapsed throughout the Pacific Ocean. Poachers are stealing the beautiful Radiated Tortoise (Astrochelys radiata), even from national parks. The unique Central American River Turtle (Dermatemys mawii), the only living representative of its family, is being eaten out of existence.

There is more to turtles than most of us know. We think of them as the quintessence of slowness. When Camille Saint-Sa‘ns assigned music to the tortoise in Carnival of the Animals, it was Jacques Offenbach's famous cancan--played at a glacial pace. But anyone who lets a careless hand get too close to an angry snapper or softshell will learn just how rapidly a turtle can move. The Big-headed Turtle (Platysternon megacephalum) of Southeast Asia can scale a slippery boulder or even climb into a tree. The Pig-nose Turtle (Carettochelys insculpta) of Australasia can dart away at four times the speed of a swimming human, and a sea turtle can fly through the water with balletic grace.

Imagine if turtles had vanished long ago, with the dinosaurs, and we knew them only from fossils. Surely we would be amazed that such bizarre creatures, sealed in bone, ribs welded to their shells, had existed; had ranged successfully almost throughout the world, in deserts, rivers, and forests, and far out into the open sea; had dug burrows that became homes for other creatures; had a role to play in the habitats where they lived. We would regret that we had missed the opportunity to see them plodding their way through ancient forests, beneath the feet of monsters.

But turtles, unlike so many other reptiles of past ages, did survive, and for many of us they are a commonplace. Some of us think of them with amusement, as comic-strip characters, plush toys for children, or dancing, top-hatted figures on a box of candy. For others, turtles are a source of food and income, whether from selling a tortoise as a pet or showing tourists a sea turtle laboriously digging its nest in the sand. For some, turtles are even an object of veneration, to be protected and fed on the grounds of a temple. Humankind sees turtles as anything but what they really are: highly evolved, remarkable creatures, necessary components of their shrinking and ever more degraded ecosystems. We in the West have ceased to be amazed by them.
