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.

The Biology of Sharks and Rays is a comprehensive resource on the biological and physiological characteristics of the cartilaginous fishes: sharks, rays, and chimaeras. In sixteen chapters, organized by theme, A. Peter Klimley covers a broad spectrum of topics, including taxonomy, morphology, ecology, and physiology. For example, he explains the body design of sharks and why the ridged, toothlike denticles that cover their entire bodies are present on only part of the rays’ bodies and are absent from those of chimaeras. Another chapter explores the anatomy of the jaws and the role of the muscles and teeth in jaw extension, seizure, and handling of prey. The chapters are richly illustrated with pictures of sharks, diagrams of sensory organs, drawings of the body postures of sharks during threat and reproductive displays, and maps showing the extent of the species’ foraging range and long-distance migrations. Each chapter commences with an anecdote from the author about his own personal experience with the topic, followed by thought-provoking questions and a list of recommended readings in the scientific literature. The book will be a useful textbook for advanced ichthyology students as well as an encyclopedic source for those seeking a greater understanding of these fascinating creatures.

Sharks in Question is a collective response to the thousands of questions about sharks received annually by scientists at Smithsonian's National Museum of Natural History. Written in a question-and-answer format accompanied by more than 100 photographs and illustrations, the book provides knowledge for a general audience as well as students of marine biology. Victor Springer provides a comprehensive review of the biology of sharks in three broad divisions: shark biology and evolutionary history, the “supersharks” notable for their life history, size, or temperament, and the interactions between sharks and humans, including the risk of shark attack.

The Amazon and Orinoco basins in northern South America are home to the highest concentration of freshwater fish species on earth, with more than 3,000 species allotted to 564 genera. Amazonian fishes include piranhas, electric eels, freshwater stingrays, a myriad of beautiful small-bodied tetras and catfishes, and the largest scaled freshwater fish in the world, the pirarucu. Field Guide to the Fishes of the Amazon, Orinoco, and Guianas provides descriptions and identification keys for all the known genera of fishes that inhabit Greater Amazonia, a vast and still mostly remote region of tropical rainforests, seasonally flooded savannas, and meandering lowland rivers. The guide’s contributors include more than fifty expert scientists. They summarize the current state of knowledge on the taxonomy, species richness, and ecology of these fish groups, and provide references to relevant literature for species-level identifications. This richly illustrated guide contains 700 detailed drawings, 190 color photos, and 500 distribution maps, which cover all genera. An extensive and illustrated glossary helps readers with the identification keys. The first complete overview of the fish diversity in the Amazon, Orinoco, and Guianas, this comprehensive guide is essential for anyone interested in the freshwater life inhabiting this part of the world.

Rays are among the largest fishes and evolved from shark-like ancestors nearly 200 million years ago. They share with sharks many life history traits: all species are carnivores or scavengers; all reproduce by internal fertilisation; and all have similar morphological and anatomical characteristics, such as skeletons built of cartilage. Rays of the World is the first complete pictorial atlas of the world’s ray fauna and includes information on many species only recently discovered by scientists while undertaking research for the book. It includes all 26 families and 633 valid named species of rays, but additional undescribed species exist for many groups. Rays of the World features a unique collection of paintings of all living species by Australian natural history artist Lindsay Marshall, compiled as part of a multinational research initiative, the Chondrichthyan Tree of Life Project. Images sourced from around the planet were used by the artist to illustrate the fauna. This comprehensive overview of the world’s ray fauna summarises information such as general identifying features and distributional information about these iconic, but surprisingly poorly known, fishes. It will enable readers to gain a better understanding of the rich diversity of rays and promote wider public interest in the group. Rays of the World is an ideal reference for a wide range of readers, including conservationists, fishery managers, scientists, fishers, divers, students and book collectors.

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.

Virtually every area of research associated with sharks and their relatives has been strongly impacted by the revolutionary growth in technology. The questions we can now ask are very different than those reported even two decades ago. Modern immunological and genetic techniques, satellite telemetry and archival tagging, modern phylogenetic analysis, GIS, and bomb dating, are just a few of the techniques and procedures that have become a part of our investigative lexicon. A modern synthesis of the biology of Chondrichthyans, Biology of Sharks and Their Relatives, Second Edition discusses significant advances in the development and application of new molecular techniques to the understanding of the phylogenetic relationships among and between these groups. The book considers the effect of global changes on the status of sharks and their relatives, and how advances in technology and analytical techniques have changed not only how we approach problem solving and scientific investigations, but how we formulate questions. The book also introduces applications of new and novel laboratory devices, techniques, and field instruments. This second edition of the award winning and groundbreaking original exploration of the fundamental elements of the taxonomy, systematics, physiology, and ecology of sharks, skates, rays, and chimera, presents cohesive and integrated coverage of key topics and discusses technological advances used in modern shark research. Offering a well-rounded picture for students and researchers, and far above competitors in scope and research, this new volume holds a wealth of data on the current status of Chondrichthyan research and provides the basis and springboard for original research.
