Overview

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.

Jim Spotila¿s new sea turtle book has an ambitious subtitle. In the enormous and ever growing literature on marine turtles, how could any single volume be a ¿Complete¿ guide to all the fundamental aspects of their biology and conservation? Ambitious, but successful. If one had to find a single book to give to a new entrant in the field of sea turtles ¿ or, for that matter, to an advanced sea turtle scientist who was normally focused upon one aspect of sea turtle biology, one locality, or one research technique, this volume would be the one to choose. It succeeds well in giving a thorough, scientific, and up-to-date overview of the field. The text of ¿Sea Turtles¿ breaks down into thirteen chapters, each with a lively or evocative title (from ¿The Seven Swimmers¿ (or should it be eight?*) to ¿Under the Shell;¿ ¿The Giant Mariner¿ to ¿Dreaming of Eden.¿ The style is highly readable, with many personal anecdotes and comments, which offer both scientific insight into what turtles are all about, and also the sense of wonder and personal dedication that is the hallmark of virtually all the players in this growing field. The scope is truly global ¿ not just literally, for there is no geographic parochialism in this book, but metaphorically also. There are not only detailed accounts of each species, but also good discussions of turtle ¿:phenomena¿ ¿ sea turtle ancestry, turtle life cycles, population stresses, navigation, migrations, the arribada phenomenon, the pluses and minuses of head-starting, and so on. An attractive feature of the book is the inclusion of a number of short biographies, with good photo portraits, of selected individuals who have made major contributions to sea turtle biology. Just a dozen or so had the honor to make ¿Spotila¿s list¿ ¿ a challenging selection task in view of the enormous number of people now doing sea turtle work, but while many real-world winners did not make the list, there were certainly no losers included! One imagines that the Spotila laureates will include this prestigious recognition somewhere near the top of their proud achievements in the next version of their personal CVs. The photography is superb. Many talented photographers contributed their work, and there are stunning marine turtle images on almost all of the 227 pages of this book, many of them taken underwater and revealing our shelled friends in their true medium, where they look so much more graceful, animated, and at ease than in the usual pictures of an exhausted, sand-covered, weeping turtle struggling to complete its duties on the nesting beach. *Reviewer¿s comment.
