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.

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.

Weighing as much as 2,000 pounds and reaching lengths of over seven feet, leatherback turtles are the world’s largest reptile. These unusual sea turtles have a thick, pliable shell that helps them to withstand great depths—they can swim more than one thousand meters below the surface in search of food. And what food source sustains these goliaths? Their diet consists almost exclusively of jellyfish, a meal they crisscross the oceans to find. Leatherbacks have been declining in recent decades, and some predict they will be gone by the end of this century. Why? Because of two primary factors: human redevelopment of nesting beaches and commercial fishing. There are only twenty-nine index beaches in the world where these turtles nest, and there is immense pressure to develop most of them into homes or resorts. At the same time, longline and gill net fisheries continue to overwhelm waters frequented by leatherbacks. In The Leatherback Turtle, James R. Spotila and Pilar Santidrián Tomillo bring together the world’s leading experts to produce a volume that reveals the biology of the leatherback while putting a spotlight on the conservation problems and solutions related to the species. The book leaves us with options: embark on the conservation strategy laid out within its pages and save one of nature’s most splendid creations, or watch yet another magnificent species disappear.

The smallest of the sea turtles, olive and Kemp’s ridleys are the only marine turtles to exhibit mass-nesting behavior, known as arribadas. This fascinating phenomenon, during which one could literally walk shell-to-shell across a beach, is considered one of the most amazing wonders of nature. In Biology and Conservation of Ridley Sea Turtles, Pamela T. Plotkin brings together the world’s experts on the genus Lepidochelys to present the first comprehensive, book-length examination of these fascinating animals. Featuring the writings of noted experts including Peter C. H. Pritchard, Jack Frazier, Rene Márquez-M., and Donna J. Shaver, the volume synthesizes over a half century of research. With chapters focused on evolution, development, genetics, physiology, reproduction, migration, and conservation, this book combines a wealth of knowledge and describes an agenda for further research. An integral part of oceanic ecosystems, ridleys present challenges for conservation. Olive ridleys are abundant in some areas and declining in others, whereas Kemp’s ridleys are endangered but slowly recovering. Both face beach-based threats and are prone to capture by commercial fisheries. Here Plotkin and her colleagues reveal the nature of these species and the steps needed to make sure they remain a permanent part of the marine environment.

The Case Of The Green Turtle

The journals of early maritime explorers traversing the Atlantic Ocean often describe swarms of sea turtles, once a plentiful source of food. Many populations had been decimated by the 1950s, when Archie Carr and others raised public awareness of their plight. One species, the green turtle, has been the most heavily exploited due to international demand for turtle products, especially green turtle soup. The species has achieved some measure of recovery due to thirty years of conservation efforts, but remains endangered. In The Case of the Green Turtle, Alison Rieser provides an unparalleled look into the way science and conservation interact by focusing on the most controversial aspect of green turtle conservation—farming. While proponents argued that farming green sea turtles would help save them, opponents countered that it encouraged a taste for turtle flesh that would lead to the slaughter of wild stocks. The clash of these viewpoints once riveted the world. Rieser relies on her expertise in ocean ecology, policy, and law to reveal how the efforts to preserve sea turtles changed marine conservation and the way we view our role in the environment. Her study of this early conservation controversy will fascinate anyone who cares about sea turtles or the oceans in which they live. -- C. Kenneth Dodd, Jr.
