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.

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.

Introduces the world of sharks, examining their characteristics, breeding, life cycle, and behavior and describing various species.

"Dive under the waves and discover everything you ever wanted to know about fascinating and fearsome sharks, as well as other creatures of the deep!" (publisher).

"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.

Upon the 100th anniversary of the most terrifying stretch of shark attacks in American history--a wave said to have been the inspiration for Jaws--comes a reissue of the classic Lyons Press account and investigation. In July 1916, a time when World War I loomed over America and New York City was in the midst of a deadly polio epidemic, the tri-state area sought relief at the Jersey shore. The Atlantic’s refreshing waters proved to be utterly inhospitable, however. In just twelve days, four swimmers were violently and fatally mauled in separate shark attacks, and a fifth swimmer escaped an attack within inches of his life. In this thoroughly researched account, Dr. Richard Fernicola, the leading expert on the attacks, presents a riveting portrait, investigation, and scientific analysis of the terrifying days against the colorful backdrop of America in 1916 in Twelve Days of Terror.

Biggest of all fish and the best equipped for hunting, sharks live in every ocean. No natural predator except the killer whale threatens them, and they possess an extraordinary physiology...including those unrivaled jaws. They have become the stuff of movies, books, and nightmares, but some of what we commonly believe is fiction, not fact. Through the examination of case histories, including gruesome attacks on man, The Jaws of Death documents the truth. It discusses why sharks are essential to the equilibrium of the marine biotope and what benefit they have provided to science and medicine. In addition to sharks, other "jaws of death" receive attention, including piranhas, crocodiles, and barracudas.
