Secret Life Of Sharks

Marine biologist Pete Klimley swims with the sharks. 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.

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.

A group of traders huddles around a pile of dried shark fins on a gleaming white floor in Hong Kong. A Papua New Guinean elder shoves off in his hand-carved canoe, ready to summon a shark with ancient magic. A scientist finds a rare shark in Indonesia and forges a deal with villagers so it and other species can survive. In this eye-opening adventure that spans the globe, Juliet Eilperin investigates the fascinating ways different individuals and cultures relate to the ocean’s top predator. Along the way, she reminds us why, after millions of years, sharks remain among nature’s most awe-inspiring creatures. From Belize to South Africa, from Shanghai to Bimini, we see that sharks are still the object of an obsession that may eventually lead to their extinction. This is why movie stars and professional athletes go shark hunting in Miami and why shark’s fin soup remains a coveted status symbol in China. Yet we also see glimpses of how people and sharks can exist alongside one another: surfers tolerating their presence off Cape Town and ecotourists swimming with sharks that locals in the Yucatán no longer have to hunt. With a reporter’s instinct for a good story and a scientist’s curiosity, Eilperin offers us an up-close understanding of these extraordinary, mysterious creatures in the most entertaining and illuminating shark encounter you’re likely to find outside a steel cage.

The first book from Internet sensation, The Life of Sharks. Putting funny words into the mouths of big fish. Dark, silly and heartwarming at turns, the Life of Sharks comics are about the daily struggles sharks encounter with their families, relationships, jobs and dating lives.

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.
