The eighty-nine cetacean species that swim our seas and rivers are as diverse as they are intelligent and elusive, from the hundred-foot-long, two-hundred-ton blue whale to the lesser-known tucuxi, ginkgo-toothed beaked whale, and diminutive, critically endangered vaquita. The huge distances these highly migratory creatures cover and the depths they dive mean we catch only the merest glimpses of their lives as they break the surface of the water. But thanks to the marriage of science and technology, we are now beginning to understand their anatomy, complex social structures, extraordinary communication abilities, and behavioral patterns. In this beautifully illustrated guide, renowned marine mammalogist Annalisa Berta draws on the contributions of a pod of fellow whale biologists to present the most comprehensive, authoritative overview ever published of these remarkable aquatic mammals. Opening with an accessible rundown of cetacean biology—including the most recent science on feeding, mating, and communication—Whales, Dolphins, and Porpoises then presents species-specific natural history on a range of topics, from anatomy and diet to distribution and conservation status. Each entry also includes original drawings of the species and its key identifiers, such as fin shape and color, tooth shape, and characteristic markings as they would appear both above and below water—a feature unique to this book. Figures of myth and—as the debate over hunting rages on—figures of conflict since long before the days of Moby-Dick, whales, dolphins, and porpoises are also ecologically important and, in many cases, threatened. Written for general enthusiasts, emergent cetacean fans, and biologists alike, this stunning, urgently needed book will serve as the definitive guide for years to come.

In this updated edition, award-winning author and whale researcher Erich Hoyt takes readers into the field for an intimate encounter with 93 species of cetaceans that make their homes in the world's oceans, rivers and lakes. Drawing on decades of firsthand experience and a comprehensive familiarity with the current revolution in cetacean studies, Hoyt provides unique insights into the life histories of whales. This new edition features descriptions of three new whale and dolphin species, along with the latest discoveries about cetacean biology and behavior, from the physical differences and adaptations among the baleen and toothed whales to their highly intelligent hunting and feeding methods. Uncovered in fascinating detail are the courtship and mating practices, family relationships and the lifelong bonds among some family members. The symphonic composer of the whale world is the humpback whale, whose complex 30-minute songs reverberate across the liquid universe of the ocean. Current research reveals that blue, fin, bowhead and other whales also sing, mostly in tones below human hearing. Using sound for navigation, some whales hunt in deep, high pressure waters while others negotiate migrations across entire ocean basins. Thoroughly updated to reflect the latest findings, this book is perfect for anyone curious about the cetacean world. Budding whale students will gain insights on how to research whales, dolphins and porpoises as well as how to save at-risk species and their increasingly damaged habitat. Encyclopedia of Whales, Dolphins and Porpoises includes: detailed profiles of 93 current species of cetaceans (3 more than in the previous edition) the story of the newly discovered Sato's beaked whale, a small black whale from the North Pacific related to the Baird's beaked whale fascinating sidebars that bring to life cetacean society and culture an enlightening discussion of the differences between dolphins and porpoises new information on the history and impact of whaling illustrations of each species by renowned artist Uko Gorter, including the three new species named in the past five years color photographs by world-famous marine photographer Brandon Cole, among others.
