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.

An epic, oversize nonfiction picture book in the vein of Bees: A Honeyed History—all about sharks and their prehistoric predecessors Sharks are some of the oldest creatures on the earth (or, rather, in its waters). This epic survey follows sharks from their earliest appearance in the Paleozoic era up through the challenges they face today. Along the way, readers will meet many different sharks from different points in history. They will get an up-close evolutionary look at what makes a shark a shark—like their skin, their teeth, their fins, and more. And they will get a crash course in archeological time, as the book mostly covers prehistoric sharks or modern-day sharks who have been around much longer than humans. Like the hammerhead, who has been patrolling tropical coastlines for more than 20 million years! With lush illustrations from Gordy Wright and meticulous research from author Miriam Forster, Sharks: A Mighty, Bite-y History is sure to delight shark lovers, science fans, and any reader who loves to discover new wonders about the world around them.

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.

"Crammed with color photos, Ritter's scientific anthem to the shark explains why fear of the creatures is misplaced, countering scare stories with detailed information about shark biology and behavior. He notes that humans kill an estimated 200 million sharks each year; he pleads for greater understanding and respect for sharks at a time when many species are threatened with extinction. Ritter is scientific director of the Shark Project, based in Germany, and is associated with the Shark Research Institute in Princeton, New Jersey, and the Shark Education and Research Center in the Bahamas." -- Publisher.

Every summer, thousands flock to the Jersey Shore for its beaches and boardwalks, but lurking in the depths beyond is a historic threat to tranquility. Dozens of shark attacks and interactions have occurred throughout Jersey Shore history that reveal bravery, heartbreak and the hubris of man. A boy paid a gruesome price for teasing a trapped shark in the first recorded attack in 1842. The three bloody attacks of 1960 left one man's limb amputated. The horrific summer of 1916 included seven attacks in a two-week span and crafted the caricature of the killer shark that remains in popular culture today. Authors Patricia and Robert Heyer dive into the history of when two apex predators, man and shark, cross paths on the shores of New Jersey.

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.

In this remarkable groundbreaking book, a documentarian and conservationist, determined to dispel misplaced fear and correct common misconceptions, explores in-depth the secret lives of sharks—magnificent creatures who play an integral part in maintaining the health of the world’s oceans and ultimately the planet. From the Jaws blockbusters to Shark Week, we are conditioned to see sharks as terrifying cold-blooded underwater predators. But as Ocean Guardian founder William McKeever reveals, sharks are evolutionary marvels essential to maintaining a balanced ecosystem. We can learn much from sharks, he argues, and our knowledge about them continues to grow. The first book to reveal in full the hidden lives of sharks, Emperors of the Deep examines four species—Mako, Tiger, Hammerhead, and Great White—as never before, and includes fascinating details such as: Sharks are 50-million years older than trees; Sharks have survived five extinction level events, including the one that killed off the dinosaurs; Sharks have electroreception, a sixth-sense that lets them pick up on electric fields generated by living things; Sharks can dive 4,000 feet below the surface; Sharks account for only 6 human fatalities per year, while humans kill 100 million sharks per year. McKeever goes back through time to probe the shark’s pre-historic secrets and how it has become the world’s most feared and most misunderstood predator, and takes us on a pulse-pounding tour around the world and deep under the water’s surface, from the frigid waters of the Arctic Circle to the coral reefs of the tropical Central Pacific, to see sharks up close in their natural habitat. He also interviews ecologists, conservationists, and world-renowned shark experts, including the founders of Greenpeace’s Rainbow Warrior, the head of the Massachusetts Shark Research Program, and the self-professed “last great shark hunter.” At once a deep-dive into the misunderstood world of sharks and an urgent call to protect them, Emperors of the Deep celebrates this wild species that hold the key to unlocking the mysteries of the ocean—if we can prevent their extinction from climate change and human hunters.
