Book Description
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.

Book Description
Maligned and misunderstood, sharks are possibly the most feared, yet the most fascinating sea creatures. Of about 350 known species of shark, only a handful are a threat to humans. In reality, it is humans who pose the greater threat, hunting and fishing some species to the verge of extinction. Diverse in appearance, they range from the tiny cookiecutter or cigar shark, to the massive whale shark. Stranger still are the rays, with names such as the banded stingaree and the Javanese cownose ray. Curiously shaped like craft from outer space, some are so highly colored they could be the creation of a whimsical painter. This book represents the most up-to-date information and thinking on our understanding of these extraordinary inhabitants of the deep - their highly developed senses and intellect, and their ecology, biology, and behavior. What is being done to protect them? In what ways are they still being exploited? Sharks and Rays highlights the advances being made in shark and ray conservation.

Book Description
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.

Book Description
At once feared and revered, sharks have captivated people since our earliest human encounters. Children and adults alike stand awed before aquarium shark tanks, fascinated by the giant teeth and unnerving eyes. And no swim in the ocean is undertaken without a slight shiver of anxiety about the very real—and very cinematic—dangers of shark bites. But our interactions with sharks are not entirely one-sided: the threats we pose to sharks through fisheries, organized hunts, and gill nets on coastlines are more deadly and far-reaching than any bite. In Sharks and People acclaimed wildlife photographer Thomas Peschak presents stunning photographs that capture the relationship between people and sharks around the globe. A contributing photographer to National Geographic, Peschak is best known for his unusual photographs of sharks—his iconic image of a great white shark following a researcher in a small yellow kayak is one of the most recognizable shark photographs in the world. The other images gathered here are no less riveting, bringing us as close as possible to sharks in the wild. Alongside the photographs, Sharks and People tells the compelling story of the natural history of sharks. Sharks have roamed the oceans for more than four hundred million years, and in this time they have never stopped adapting to the ever-changing world—their unique cartilage skeletons and array of super-senses mark them as one of the most evolved groups of animals. Scientists have recently discovered that sharks play an important role in balancing the ocean, including maintaining the health of coral reefs. Yet, tens of millions of sharks are killed every year just to fill the demand for shark fin soup alone. Today more than sixty species of sharks, including hammerhead, mako, and oceanic white-tip sharks, are listed as vulnerable or in danger of extinction. The need to understand the significant part sharks play in the oceanic ecosystem has never been so urgent, and Peschak’s photographs bear witness to the thrilling strength and unique attraction of sharks. They are certain to enthrall and inspire.
