Sea turtles have existed for millions of years, making them fascinating subjects of study. In the last 20 years, the science of sea turtle biology has expanded at an exponential rate, leading to major advances in many areas. This book synthesizes the results of these advances and focuses on how these endangered marine reptiles operate in, adapt to, and are dependent upon particular features of their marine environment. New technology in data gathering, such as DNA analyses, remote sensing, and physiological monitoring techniques, has led to a much greater understanding of the biology of the sea turtle at all stages of their life history.
Areas of advancement discussed in The Biology of Sea Turtles include:
o Population genetics and phylogeny
o Sensory biology
o Migration and orientation hatchling behavior
o Age and growth
o Reproduction and endocrinology sex determination
o Diving physiology
o Osmoregulation
The book also addresses the endangered status of sea turtles and deals with threats to their survival posed by man-made changes to ocean and coastal zones. The first book of its kind, The Biology of Sea Turtles fills a substantial void in the literature, and will be of great value and interest to marine biologists, environmentalists, and conservationists.

For more than a hundred million years, sea turtles have been swimming in the world's oceans. These magnificent, long-lived creatures spend their lives in the water, coming ashore to lay their eggs. Upon hatching, the baby turtles leave the nest and enter a dangerous world of storms and predators. The females will return to the same beach to lay their own eggs when they reach maturity a decade later. Today, there are seven species of sea turtle: the grass-eating green turtle; the sea sponge-eating hawksbill; the olive ridley; the Kemp's ridley, which is the smallest species; the loggerhead; the flatback of Australia; and the giant leatherback. Having escaped the mass extinction that wiped out the dinosaurs, these ancient reptiles today face new dangers that threaten their survival: pollution, hunting, and the destruction of their nesting grounds. Will this century be the last to witness their majesty? Will succeeding generations live in a world devoid of their graceful presence?

Marine biologist James R. Spotila has spent much of his life unraveling the mysteries of these graceful creatures and working to ensure their survival. In "Sea Turtles," he offers a comprehensive and compelling account of their history and life cycle based on the most recent scientific data--and suggests what we can do now to save them. From the Kemp's ridley, which nests on a single beach on Mexico's Gulf Coast, to the nomadic leatherback, which can weigh up to a ton and is in the most imminent danger of extinction, Spotila offers a vivid description of their diets and mating habits, and the conservation efforts being made on their behalf. Illustrated with stunning color photographs by the world's leading nature photographers, "Sea Turtles" will inform and inspire readers of all ages everywhere.

Written by two of the Southeast's foremost authorities on sea turtle conservation, this is an accessible, fully illustrated guide to the species that frequent the Atlantic and Gulf Coasts of the United States. No one who encounters a sea turtle soon forgets it. The leatherback, for instance, can grow to huge proportions, commonly approaching eight feet in length and more than half a ton in weight. Powerful swimmers, they are also among the deepest divers of all air-breathing sea creatures. Despite these assets, the survival of the leatherback, like that of all sea turtle species, is under constant threat from commercial fishing operations, overdevelopment of nesting grounds, pollution, and predation by introduced species. The guide opens with comprehensive coverage of the sea turtle's evolution, juvenile and adult life cycles, nesting, diet and feeding, disease and parasites, predators, and conservation issues. Each subsequent chapter is dedicated to a particular turtle species: loggerhead, leatherback, Kemp's ridley, green sea turtle, hawksbill, and olive ridley. The account of each species describes distribution, habitats, general appearance, life history and behavior, and conservation. For each species, photographs of hatchlings and adults and a map showing distribution and migration provide further information. Sea turtles have been swimming the seas for one hundred million years. Yet all of the species in this book - indeed, all sea turtles worldwide - are on U.S. and international endangered lists. Biologists Carol Ruckdeschel and C. Robert Shoop have dedicated their careers to learning about sea turtles - and to ensuring that we understand that we are stakeholders in the fate of these ancient creatures. With this guide in hand, readers will be better equipped to understand sea turtle biology and support sea turtle conservation efforts.
