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.

Humans aside, dolphins, whales, and porpoises are often considered to be the smartest creatures on Earth. Science and nature buffs are drawn to stories of their use of tools, their self-recognition, their beautiful and complex songs, and their intricate societies. But how do we know what we know, and what does it mean? In Deep Thinkers, renowned cetacean biologist Janet Mann gathers a gam of the world’s leading whale and dolphin researchers—including Luke Rendell, Hal Whitehead, and many more—to illuminate these vital questions, exploring the astounding capacities of cetacean brains. Diving into our current understanding of and dynamic research on dolphin and whale cognition, communication, and culture, Deep Thinkers reveals how incredibly sophisticated these mammals are—and how much we can learn about other animal minds by studying cetacean behavior. Through a combination of fascinating text and more than 150 beautiful and informative illustrations, chapters compare the intelligence markers of cetaceans with those of birds, bats, and primates, asking how we might properly define intelligence in nonhumans. As all-encompassing and profound as the seas in which these deep cetacean cultures have evolved, Deep Thinkers is an awesome and inspiring journey into the fathoms—a reminder of what we gain through their close study, and of what we lose when the great minds of the sea disappear.

In the Encyclopedia of Whales, Dolphins and Porpoises, award-winning author and whale researcher Erich Hoyt takes readers into the field for an intimate encounter with some 90 species of cetaceans that make their homes in the world's oceans. 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 these compelling marine mammals. Here are 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. The courtship and mating practices, family relationships and the lifelong bonds among some family members are fascinating. The symphonic composer of the whale world is the humpback whale, whose complex 30-minute songs reverberate across the liquid universe of the ocean. Some cetaceans survive deep diving and negotiate lengthy migrations across oceans. This book is a fascinating compilation of the latest data on cetaceans and an impassioned argument for the ongoing need for international protection of at-risk populations and their increasingly damaged habitat. Encyclopedia of Whales, Dolphins and Porpoises includes: detailed profiles of 90 current species of cetaceans a report on the newly discovered species in the genus Berardius, a small black form 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 color photographs by world-famous marine photographer Brandon Cole, among others.

The first edition of the widely praised Marine Protected Areas for Whales, Dolphins and Porpoises, published in 2005, led to numerous new marine protected area proposals and a number of notable conservation successes around the world. In this completely revised and expanded second edition, new developments in the Mediterranean, Caribbean and Pacific are described, as well as future directions for High Seas protection. New sections show how to design and manage MPAs in an ever noisier ocean subject to climate change, increased shipping and hydrocarbon exploration. The process of protected area creation for cetaceans has been accelerated and more than 200 exciting new places are detailed in this edition. This book provides a route map for MPA managers, as well as countries, to meet the ambitious targets for highly protected MPA networks by 2012 and 2020. This book is a key conservation tool and a springboard for worldwide change in human attitudes toward the world ocean where all life originated and where the majority of life on Earth still lives.
