The essential book for everyone interested in sharks, from the expert requiring a major reference work, to the layperson fascinated by their beauty, biology and diversity. Packed with unique colour illustrations, line drawings and photographs, the book is well-presented and easy to use. It is currently the only single guide to cover over 500 of the world's shark species. It incorporates the most recent taxonomic revisions of many shark families, featuring not only many species that were only described in recent years, but several more that are still awaiting their scientific names. Its production is timely. Overfishing and the shark fin trade have pushed sharks into the most threatened categories of marine animals. Their depletion has serious implications for the stability of marine ecosystems. Some species are now listed in international environmental agreements, including the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), and they are becoming a management priority for many regional fisheries management organisations. Implementation of conservation and fisheries management measures, and international trade regulation is impossible without a good identification guide.

This is an extensively rewritten, revised and updated version of the original FAO Catalogue of Sharks of the World. The present volume reviews all 15 families, 25 genera and 57 species of living bullhead, mackerel and carpet sharks (orders Heterodontiformes, Lamniformes and Orectolobiformes - the non-carcharhinoid galeomorph sharks), including certain well-established but currently undescribed species mainly from Australia. Accounts for all orders, families and genera are given and all keys to taxa are fully illustrated. Information under each species account includes: valid modern names and original citation of the species (or subspecies); synonyms; the official FAO names for the species in English, French and Spanish; a lateral view and often other useful illustrations; field marks; diagnostic features; distribution, including a GIS map; habitat; biology; size; interest to fisheries and human impact; local names when available; a remarks section when necessary; and literature. The volume is fully indexed and also contains sections on terminology and measurements including an extensive glossary, a list of species by FAO Statistical Areas, an appendix on shark preservation and an extensive bibliography. (Vol. 1 and Vol. 3 are in preparation).

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.

This important and exciting title represents the first authoritative volume focussed on pelagic (open ocean) sharks as a group. Virtually every pelagic shark expert in the world has contributed to this landmark publication which includes the latest data and knowledge on pelagic shark biology, fisheries, management, and conservation. Pelagic sharks face unprecedented levels of exploitation in all the world's oceans through both direct fisheries and by-catch, and effective management for these species is contingent upon solid science and data, which this book brings together for the first time. All those involved in shark biology will need to have a copy of this book.

Which species of sharks live within 500 nautical miles of North American shores, and what do we know about them? Jos? I. Castro's The Sharks of North America is the first comprehensive book in sixty years to address these questions, and it does so with unrivaled authority and aesthetic detail. The 135 comprehensive species accounts summarize the present knowledge. Each begins with the etymology of a species' common and scientific names, followed by the description, identifying characteristics, geographic range, biology, reproduction, location of nurseries, growth and longevity, and relation to humans. These accounts synthesize decades of research and first-hand examination of sharks collected in fisheries and research operations across the continent. They are thorough, current, and dispel many myths and misunderstandings found in the scientific and popular literature. Each species is illustrated by one or more original profile figures in color, augmented by images of the snout, upper and lower teeth, and dermal denticles. The stunning color illustrations have been painted directly from freshly dead sharks or Castro's photographs of live or fresh specimens. Their anatomical accuracy and true-to-life coloration are unmatched. The detailed pen and ink drawings of the snout and teeth are crucial aids to species identification, as are the exquisite scanning electron microphotographs of dermal denticles. The Sharks of North America will serve as the standard reference on sharks for the twenty-first century and is certain to become the primary source of information for anyone interested in sharks, from professional biologists and conservationists to students, informed laypersons, and fishermen.
