He was one of the first scientists to free-dive among sharks, and he has spent nearly thirty years studying shark behavior, sometimes swimming in schools of several hundred sharks. From his firsthand observations he has learned that sharks are not the vicious man-eaters that we imagine, but fascinating animals with complex behaviors. Most people who think of sharks at all think immediately of great white sharks. But there are more than four hundred species of shark. Dr. Klimley has studied several species, most notably the great white and the hammerhead. (He describes the great white as the athlete among sharks, and the hammerhead as the Ph.D. of the shark world.) In The Secret Life of Sharks Dr. Klimley reveals the significant discoveries he made about hammerhead navigation and great white eating habits. By studying hammerheads gathered around underwater seamounts, Dr. Klimley learned that hammerheads rely on sophisticated tracking of ocean-floor magnetism to navigate. His long-term study of great white sharks off the California coast demonstrated that these huge sharks prefer to eat seals and sea lions because of the energy contained in their fatty bodies. They are selective eaters, not the man-eaters we expect, and they sometimes go weeks between meals. But Dr. Klimley did observe a ritualized behavior that great whites practice in order to avoid deadly disputes over prey that one shark has captured and another wants. Although we have learned a great deal about shark behavior, says Dr. Klimley, there is much that we do not know. Unfortunately we are destroying these magnificent creatures of the deep through overfishing and degradation of the oceans. Already some populations of sharks have declined steeply. Vividly written by one of the foremost authorities on sharks, The Secret Life of Sharks is a fascinating account of some of the world's most magnificent animals.

Available in PDF, EPUB and Kindle. Book excerpt: At once feared and revered, sharks have captivated people since our earliest human encounters. Children and adults alike stand awed before aquarium shark tanks, fascinated by the giant teeth and unnerving eyes. And no swim in the ocean is undertaken without a slight shiver of anxiety about the very real—and very cinematic—dangers of shark bites. But our interactions with sharks are not entirely one-sided: the threats we pose to sharks through fisheries, organized hunts, and gill nets on coastlines are more deadly and far-reaching than any bite. In Sharks and People acclaimed wildlife photographer Thomas Peschak presents stunning photographs that capture the relationship between people and sharks around the globe. A contributing photographer to National Geographic, Peschak is best known for his unusual photographs of sharks—his iconic image of a great white shark following a researcher in a small yellow kayak is one of the most recognizable shark photographs in the world. The other images gathered here are no less riveting, bringing us as close as possible to sharks in the wild. Alongside the photographs, Sharks and People tells the compelling story of the natural history of sharks. Sharks have roamed the oceans for more than four hundred million years, and in this time they have never stopped adapting to the ever-changing world—their unique cartilage skeletons and array of super-senses mark them as one of the most evolved groups of animals. Scientists have recently discovered that sharks play an important role in balancing the ocean, including maintaining the health of coral reefs. Yet, tens of millions of sharks are killed every year just to fill the demand for shark fin soup alone. Today more than sixty species of sharks, including hammerhead, mako, and oceanic white-tip sharks, are listed as vulnerable or in danger of extinction. The need to understand the significant part sharks play in the oceanic ecosystem has never been so urgent, and Peschak’s photographs bear witness to the thrilling strength and unique attraction of sharks. They are certain to enthrall and inspire.

Book excerpt: From ancient megalodons to fearsome Great Whites, this book tells the complete, untold story of how sharks emerged as Earth’s ultimate survivors, by world-leading paleontologist John Long. “Will keep you on the edge of your seat from its first page to its last page.”—Jared Diamond, Pulitzer Prize–winning author of Guns, Germs, and Steel Sharks have been fighting for their lives for 500 million years and today are under dire threat. They are the longest-surviving vertebrate on Earth, outlasting multiple mass extinction events that decimated life on the planet. But how did they thrive for so long? By developing superpower-like abilities that allowed them to ascend to the top of the oceanic food chain. John Long, who for decades has been on the cutting edge of shark research, weaves a thrilling story of sharks’ unparalleled reign. The Secret History of Sharks showcases the global search to discover sharks’ largely unknown evolution, led by Long and dozens of other extraordinary scientists. They embark on digs to all seven continents, investigating layers of rock and using cutting-edge technology to reveal never-before-found fossils and the clues to sharks’ singular story. As the tale unfolds, Long introduces an enormous range of astonishing organisms: a thirty-foot-long shark with a deadly saw blade of jagged teeth protruding from its lower jaws, a monster giant clams crusher, and bizarre sharks fossilized while in their mating ritual. The book also includes startling new facts about the mighty megalodon, with its sixty-six-foot-long body, massive jaws, and six-inch serrated teeth. With insights into the threats to sharks today, how they contribute to medical advances, and the lessons they can teach us about our own survival, The Secret History of Sharks is a riveting look at scientific discovery with ramifications far beyond the ocean.

Book excerpt: “A quintessential summer read.” —Marie Claire A warm and wonderfully vivid novel about taking second chances—in life and in the sea One summer day on the beach in Florida, two extraordinary things happen to Maeve Donnelly. First, she is kissed by Daniel, the boy of her dreams. Then, she is bitten by a blacktip shark. Eighteen years later, Maeve has thrown herself into her work as a world-traveling marine biologist discovering more about the minds of misunderstood sharks. But when Maeve returns home to the legendarily charming and eccentric Hotel of the Muses where she was raised by her grandmother, she finds more than just the blood orange sunsets and key lime pies she’s missed waiting for her. While Maeve has always been fearless in the water, on land she is indecisive. A chance meeting on the beach with a plucky, irresistible little girl who is just as fascinated by the ocean as Maeve was growing up leaves her at a crossroads: Should she re-kindle her romance with Daniel, the first love she left behind when she dove into her work? Or indulge in a new romance with her colleague, Nicholas, who turns up in her hometown to investigate an illegal shark-finning operation? Set against the intoxicating backdrop of palm trees, calypso bands, and perfect ocean views, The Shark Club is a story of the mysterious passions of one woman’s life: her first love and new love; the sea and sharks that inhabit it.

Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Sharks and Rays is a comprehensive resource on the biological and physiological characteristics of the cartilaginous fishes: sharks, rays, and chimaeras. In sixteen chapters, organized by theme, A. Peter Klimley covers a broad spectrum of topics, including taxonomy, morphology, ecology, and physiology. For example, he explains the body design of sharks and why the ridged, toothlike denticles that cover their entire bodies are present on only part of the rays’ bodies and are absent from those of chimaeras. Another chapter explores the anatomy of the jaws and the role of the muscles and teeth in jaw extension, seizure, and handling of prey. The chapters are richly illustrated with pictures of sharks, diagrams of sensory organs, drawings of the body postures of sharks during threat and reproductive displays, and maps showing the extent of the species’ foraging range and long-distance migrations. Each chapter commences with an anecdote from the author about his own personal experience with the topic, followed by thought-provoking questions and a list of recommended readings in the scientific literature. The book will be a useful textbook for advanced ichthyology students as well as an encyclopedic source for those seeking a greater understanding of these fascinating creatures.
