From Publishers Weekly

Starred Review. MacArthur fellow and John Burroughs Award–winner Safina (Song for the Blue Ocean) presents an impassioned account of the plight of ocean-dwelling turtles, especially the largest, the leatherback, "the closest thing we have to a living dinosaur." Leatherbacks, which can weigh over a ton, range the oceans to nesting sites on beaches along the Atlantic and Pacific seaboards. Safina travels to many of these sites, bringing the reader into the turtles' world as he describes how the females leave the ocean, cross sandy beaches, dig huge pits using their flippers as spades, lay their eggs and then creep back into the sea. He shows how precarious this world is; nature's dangers are always present, but it's human activities that threaten the turtles with extinction: poaching, longline fishing nets in which the turtles can drown and depletion of the turtles' food supply due to overfishing and global warming. There are remedies, such as intensive nest-saving programs, but these take time to implement, and time is running out for the turtles. Safina's eloquent book is a battle cry in the struggle for the survival of one of the world's most beautiful and endangered creatures. Maps. (June 27)

From School Library Journal

Adult/High School–This book is Safina's personal journal of the migration of the leatherback, loggerhead, and green turtles. These aquatic creatures of reptilian descent wander throughout the Atlantic and Pacific oceans. Eventually they die in captivity because they don't understand boundaries. This limitless ocean life is in jeopardy due to long-line fishing, poaching, and commercial development along the beaches of Trinidad and Mexico, where they nest. The author is passionate about conservation efforts, describing the eco-tourist work of Nature Seekers and the legal efforts of Oceana in protecting the now critically endangered leatherback turtles. More than a chronicle of attempts to save the species, Turtle captures the physical magnitude of these ancient creatures and the repetitive calm of their endless travels. Safina's simple and deeply personal style captures both the mystery of the leatherbacks' life cycle and the need to develop a global understanding of their plight to survive. This title will quickly become a part of the classroom libraries of those teaching life science and ecology.–Brigeen Radoicich, Fresno County Office of Education, CA

This book is an amazing story of survival....over thousands of years.
I found this the easiest to read of Carl Safina's books,all of which are extemely well written.
The things that I learned about the leatherbacks in particular were well worth the price of the book.
Carl Safina makes you care about the turtles and feel their struggles even if you've never seen a turtle before.

5.0étoiles sur 5 Traipsing after turtles, Juil 17 2007
Par Stephen A. Haines (Ottawa, Ontario Canada) - Voir tous mes commentaires
(TOP 10 REVIEWER)    (REAL NAME)   
The human diaspora across the planet has been Nature's most jarring event since the Cretaceous. Not since an asteroid slammed into the Caribbean 65 million years ago has anything exceeded what our species has done to upset the diversity of life. A mysterious group of animals, leftovers from that bolide, is revealing its secrets to enquiring scientists. The sea-going turtles, whose peregrinations around the world's oceans, are revealing new information about their enigmatic lives. Carl Safina followed the turtles and the people studying them to describe the findings and what they mean. This brilliant account reveals turtle life and the threats they endure.

After reminding us that only seven species of sea turtle remain, Safina visits the Caribbean to describe the great Leatherbacks coming ashore and nesting. Emerging through the night's surf, she finds a particular spot, one which may require more than one attempt, then with her back to the site, uses her rear flippers to blindly scoop out a hole to drop her eggs. Safina describes his wonder at her ability to do this without seeing the effect of her digging. Not all turtles manage this without mishap, and in a few cases the caring observers do the digging for her. In either case she drops her eggs, covers them with sand in a way to camouflage the spot, then returns to the sea. From the surf line, she swims away to some unknown destination. When the eggs hatch, the surviving young follow her to the sea. For the males, it's the last time they will feel land under their flippers.

The destination long remained a mystery until tagged turtles began appearing thousands of kilometres away. Safina joins a boat seeking Swordfish over the Canadian Grand Banks as a means of finding the giant turtles. Leatherbacks plying these waters are of Caribbean origin. Those females feed on Cannonball Jellyfish along the Carolinas before shifting north, later to cruise the vastness of the Atlantic to the Azores. It's a fabulous migration, but there are bigger surprises in store.

Along the eastern Pacific, Leatherbacks and other species were once common. Nature's most voracious predator has sharply reduced their number, chiefly by removing eggs just after they're laid. Villagers consumed or sold them in vast numbers. After a tour of a miniscule beach nesting site in Costa Rica, Safina meets with various students of turtle habits. He flies with Sandy Lanham and Laura Sarti to count turtles on the Mexican Coast, where lengthy beaches no longer experience turtle numbers that once was the case. To learn what has happened to them, Safina must cross the Pacific to Papua on the west end of New Guinea. With researchers working in the area with local people, he learns of ways poverty-stricken villagers can be employed to assist in saving turtles. Here, where humans might have first contacted the Leatherback after over 100 million years without a serious enemy, turtles exhibit their vulnerability to our predatory ways. The Pacific Leatherbacks are beset by those who don't even intend it. Longliner fishing boats string over 1.4 billion hooks per year on lines running to 90 kilometres length. The hooks snag flippers or are swallowed with lines. Turtles need air, just like us, but drown before the lines are brought up. Exact statistics are hard to come by, Scafina notes, but the evidence points to these boats as the most destructive force to turtles after egg poaching.

The author notes, however, that cures are available to help restore turtle populations. Beaches in some nations are declared "off limits" and patrolled. New hook designs that catch fish without snagging turtles have been developed, but need universal application - a difficult task with conservative fishermen. In Florida, shoreline communities have learned to douse lights to protect nesting sites - otherwise the hatchlings cannot find the sea. Incorporating local help has proven effective by showing how tourism and controlled collection can bring in more money than simple predation produces. In some species, there have been gains in new populations. Are the rising numbers significant? They apply only to certain species and locations. The greatest obstacle is the issue of turtle maturity, since breeding adults may take a human generation to start laying eggs. It means patience, dedication and continuing watchfulness on conditions are required. An elusive factor is what effect climate change will have on beaches and the sealife the turtles need to survive.
