Since the award-winning first volume, The Biology of Sharks and Their Relatives, published in 2004, the field has witnessed tremendous developments in research, rapid advances in technology, and the emergence of new investigators beginning to explore issues of biodiversity, distribution, physiology, and ecology in ways that eluded more traditional studies. As an entirely new companion volume, Sharks and Their Relatives II: Biodiversity, Adaptive Physiology, and Conservation brings you up to speed on these significant changes, specifically examining how elasmobranch fishes – the sharks, skates, rays, and chimaeras – successfully survive in a wide range of habitats. Emphasizes Conservation of Threatened Species This multidisciplinary volume begins by examining elasmobranch biodiversity patterns and their integrated sensory systems. It then explores the physiological adaptations – from unique sensory modalities to compensatory mechanisms for physiological and environmental stress – that make these animals particularly well-suited for the range of habitats where they are found, in both oceanic and freshwater realms. Features Established Researchers and Introduces New Pioneers in the Field The book then considers the human interactions and anthropogenic effects on worldwide elasmobranch populations and the potential extinction risks posed by increasing threats from changes in habitat, changes in water chemistry, and growing commercial exploitation. This text truly is unrivaled in terms of coverage and readability, and it is a must-have reference for marine biologists, fishery scientists, oceanographers, and also marine, zoo, and aquarium veterinarians. To address subject areas and subdisciplines where coverage was absent or superficial in volume one, Jeffrey Carrier and associates have assembled in the current volume a collection of works that reveal patterns of biodiversity, the physiological attributes that contribute to elasmobranchs’ successful exploitation of oceanic and freshwater realms, and the unique issues associated with the interaction between elasmobranchs and humans, all of this with overarching attention to issues of conservation. "We begin with chapters examining biodiversity. We have chosen to approach this discussion by presenting elasmobranchs as inhabitants of the range of zoogeographic provinces, realizing that significant overlap may occur for more pelagic species. This realization was reflected in the dialogue that occurred during preparation of the book between our chapter authors, and the recognition that many species simply cannot be confined to a specific habitat or range of habitats. We then continue by examining some of the unique physiological adaptations that allow these animals to exploit the range of habitats where they are found, from unique sensory modalities to compensatory mechanisms for physiological and environmental stress. "Our concluding section presents some of the challenges faced by members of these groups. We have asked our authors to consider human interactions and anthropogenic effects on worldwide populations and the potential extinction risks posed from survival under increasing threats from changes in habitat, changes in water chemistry, and increasing commercial exploitation. Conservation of species under threat remains a theme throughout the book. "Our authors represent an international group of investigators including established scientists whose work has been widely published and respected, and emerging younger scientists who have exploited recent advances in technology to ask and answer new questions as well as offering new insights and interpretations to enduring problems in the fields of ecology and physiology. We have asked them to be speculative and challenging, and we have asked them to predict future areas for investigation in hopes that their work will both inspire and provoke additional studies of these fascinating animals." - from the Preface

Do sharks lay eggs or give birth to live young? Do sharks sleep? How long do they live? How likely are shark attacks? This book answers your questions about some of nature’s most misunderstood animals. Answering every conceivable question about sharks, authors Gene Helfman and George H. Burgess describe the fascinating biology, behavior, diversity (there are more than 1,000 species worldwide), and cultural importance of sharks, their close relationship to skates and rays, and their critical role in healthy ecosystems. Helfman and Burgess take readers on a round-the-world tour of shark habitats, which include oceans as well as lakes and even rivers (as far up the Mississippi as St. Louis). They describe huge, ferocious predators like (Great) White and Tiger sharks and species such as Basking and Whale sharks that feed on microscopic prey yet can grow to lengths of more than 40 feet. The mysterious and powerful Greenland shark, the authors explain, reaches a weight of 2,200 pounds on a diet of seal flesh. Small (less than 2-foot long) Cookiecutter sharks attack other sharks and even take a chunk out of the occasional swimmer. Despite our natural fascination with sharks, we have become their worst enemy. Many shark species are in serious decline and a number are threatened with extinction as a result of overfishing and persecution. Sharks: The Animal Answer Guide presents a perfect mix of current science, history, anthropology, intriguing facts, and gripping photographs. Whether your fascination with sharks stems from fear or curiosity, your knowledge of these animals will improve immensely when you consult this book.

This book reviews the current status of, and threats to, shark populations globally with special reference to the basking shark and the great white shark. This book outlines why sharks are a valuable resource, identifies threats to sharks and where they occur and reviews what we need to know about sharks in order to protect them. Fisheries management procedures are investigated to target areas requiring future research and implementation. Conservation initiatives, legislation, and international agreements are reviewed and future measures suggested. Case histories on the basking shark and the great white shark detail threats specific to these species and identify research and management requirements.

Sharks are probably the most misunderstood animals on the planet. We all still have a lot to learn about these fascinating creatures, which are sadly more seriously threatened with extinction and in greater need of conservation and management action than any other major group of vertebrates. We have produced this guide not just because we and so many other people love sharks. It is also because their identification, whether of living animals, fishery catches or body parts sold at markets, is an essential tool to support shark conservation, fisheries management and international trade regulation, prevent further depletion of stocks, and enable their recovery. ● the first pocket guide to all 501 shark species ● all species illustrated and described ● handy, compact format with concise text ● a six-page guide to shark teeth identification ● an eight-page guide to the identification of the shark fins most commonly encountered in the fin trade Colour plates are by Marc Dando from the hugely acclaimed Sharks of the World: A Fully Illustrated Guide.

The definitive identification guide to the sharks of the world The shark is undeniably the 'lord of the seas', having existed unchanged for 350 million years. Not only is it the biggest of fish, it is also the best equipped for hunting down and destroying its prey. It is capable of living in all waters shallow or deep, tropical or temperate, fresh or salt, and unlike most animals, it has no natural predators apart from the Killer Whale. Set to become a classic natural history title, Collins Field Guide to Sharks describes and illustrates the world's 530 species of shark. Shark families are grouped together and for each individual species there is detailed identification information, and original colour illustration, and a distribution map showing where in the world that species can be found. Covering all aspects of these extraordinary creatures, from their behaviour, breeding, feeding and ecology, right through to the impact of humans on sharks throughout the world, this is one of the most important shark books ever written.
