Volume 2: This is the second volume of an extensively rewritten, revised, and updated version of the original FAO Catalogue of Sharks of theWorld. The present volume reviews all 15 families 25 genera and 57 species of living bullhead, mackerel and carpet sharks (orders Heterodontiformes, Lamniformes and Orectolobiformes), that is, the non-carcharhinoid galeomorph sharks, including certain well-established but currently undescribed species mainly from Australia.

Field Identification Guide to the Sharks and Rays of the Red Sea and Gulf of Aden

This volume presents a fully illustrated field guide for the identification of the sharks and rays most relevant to the fisheries of the Red Sea and Gulf of Aden. An extensive literature review and two field surveys in the region were carried out for the preparation of this document. A total of 49 sharks and 45 batoids reliably reported for the region are listed and those common in the fisheries or likely to be found through fisheries operations are fully treated. The guide includes sections on technical terms and measurements for sharks and batoids, and fully illustrated keys to those orders and families that occur in the region. Color plates for a large number of the species are included.

The 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.

Whale Sharks

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.

Sharks in the Arts

This book is the most thorough exploration to date of the many ways in which a wild creature has been absorbed, reimagined and represented across the ages in all of the major art forms. The authors consider not only how the identity of sharks in the natural environment became incorporated into a cultural environment but also how sharks came to be considered the most feared creatures in the open oceans as a consequence of this incorporation. Yet sharks are especially important in helping to maintain a balance that is essential to the health of the oceans. The book begins with a treatment of the three sharks at the top of global shark-attack files from scientific, economic and environmental perspectives. Subsequent chapters engage with cultural representations of sharks in poetry, drama, art, novels, screenplay adaptations and films. Through an exploration of the ways in which sharks have been represented in human culture through the centuries, this book alerts the global community to the importance of sharks as a common cultural heritage. It aims to change perceptions of sharks so that they can become more revered than feared. The authors of this book argue that an increased understanding of sharks should lead to the development of better strategies for shark and human interactions. This book will be of great interest to researchers and students of the Environmental Humanities, Cultural History and the Arts. It is also excellent supplementary reading for courses in Zoology and Marine Science.
