Book Description
The True Nature of Sharks is a full scale exploration of wild shark behavior. Drawn from fifteen years of observing sharks underwater as animals and individuals, it reveals a new dimension of understanding of their lives. This timely book will make the mysterious world of sharks come alive for you.You will learn how their complex actions reveal that sharks are thinking, rather than acting on instinct alone. For they are not the dangerously stupid automatons that popular media will have us believe. Neither are they monsters, nor the cold and senseless creatures described by fisheries science.They are ordinary animals, thinking about the events in their lives and responding intelligently.By their actions, sharks reveal that they are self-aware, form companionships, make swift decisions depending on the circumstances, and can plan to influence an event in the future. They enjoy socializing, communicate through posturing and gestures, and are capable of influencing each other. They can become highly emotional, yet are peaceful among themselves. Unlike many other animals, including humans, they do not fight!If you love discovering new, intelligent wildlife behavior, you will love this beautifully written and illustrated book, which presents a wealth of unexpected insights and tantalizing implications as it integrates field observations with facts from other branches of science. The author's clear writing and vivid prose makes you feel as if you are there with the sharks in the submarine realm, and the detailed analysis of the behavior of these important and unusual animals is captivating.As one of the world's few shark ethologists, the author is the only researcher to study sharks long-term by observing them underwater. Already familiar with terrestrial wildlife, she saw at once that they are very different from the mammals and birds we know best, and after several intriguing incidents with them, launched an intensive, seven year study. Following the precepts of cognitive ethology, she kept track of about six hundred reef sharks, and could recognize more than three hundred on sight. To supplement her findings, she watched wild tiger, bull, and lemon sharks for shorter periods. Her methods resulted in her being credited with finding a way to study sharks without killing them, and the revelation that sharks are sensitive, conscious animals provides another important reason to protect them from being fished into extinction.Once you understand the true nature of these unusual animals, you will never think of them in the same way again."Awareness of the cognitive abilities of these animals forever changes our perception of them, and their place in nature, and ours."~ Alan C. Kamil ~ Emeritus Professor of Biology and Psychology,University of Nebraska

Book Description
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.

Book Description
A journalist's obsession brings her to a remote island off the California coast, home to the world's most mysterious and fearsome predators--and the strange band of surfer-scientists who follow them Susan Casey was in her living room when she first saw the great white sharks of the Farallon Islands, their dark fins swirling around a small motorboat in a documentary. These sharks were the alphas among alphas, some longer than twenty feet, and there were too many to count; even more incredible, this congregation was taking place just twenty-seven miles off the coast of San Francisco. In a matter of months, Casey was being hoisted out of the early-winter swells on a crane, up a cliff face to the barren surface of Southeast Farallon Island-dubbed by sailors in the 1850s the "devil's teeth." There she joined Scot Anderson and Peter Pyle, the two biologists who bunk down during shark season each fall in the island's one habitable building, a haunted, 135-year-old house spackled with lichen and gull guano. Two days later, she got her first glimpse of the famous, terrifying jaws up close and she was instantly hooked; her fascination soon yielded to obsession-and an invitation to return for a full season. But as Casey readied herself for the eight-week stint, she had no way of preparing for what she would find among the dangerous, forgotten islands that have banished every campaign for civilization in the past two hundred years. The Devil's Teeth is a vivid dispatch from an otherworldly outpost, a story of crossing the boundary between society and an untamed place where humans are neither wanted nor needed.

Book Description
Whale sharks are the largest of all fishes, fascinating for comparative studies of all manner of biological fields, including functional anatomy, growth, metabolism, movement ecology, behavior and physiology. These gentle ocean giants have captured the interest of scientists and the imagination of the public, yet their future is uncertain. The conservation status of whale sharks was upgraded to Endangered on the IUCN Red List and the species faces a range of intense threats from human activities. Can these iconic living animals, who have survived for millions of years, survive us? Written by the world’s leading experts in whale shark biology, ecology, and conservation, Whale Sharks: Biology, Ecology and Conservation is the first definitive volume about the world's biggest fish. Chapters include discussions of satellite-linked tags, used to track whale shark movements; genetic sequencing, to examine evolutionary adaptations; even the use of underwater ultrasound units to investigate the species’ reproduction. The editors hope that by collating what is known, they can make it easier for future researchers, conservationists, and resource managers to fill some of the remaining knowledge gaps, and provide the information they need to join the team. As you work your way through this book, we hope that you will develop a sense of awe and marvel at all of our good fortune to share the ocean, and the planet, with this utterly extraordinary species.

From the bestselling author of Jaws comes a firsthand guide to one of the most feared—and often misunderstood—animals: sharks! In direct and accessible prose, Peter Benchley sets the record straight about the many types of sharks (including the ones that pose a genuine threat to us), the behavior of sharks and other sea creatures we fear, the odds against an attack, and how to improve them even further. He also teaches us how to swim safely in the ocean by reading the tides and currents and respecting all the inhabitants. Here are the lessons Peter has learned, the mistakes he has made, the danger he has faced—and the spectacular sights he has seen in the world’s largest environment. The book includes 16 pages of black-and-white photographs.
