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.
