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.

Presents information on how to tell the difference between dolphins and porpoises, even though they are similar in many ways.

Dolphins and porpoises look very similar, but while these mammals share some features they aren't even in the same family. From tooth and jaw shape to the way they chat with one another, these amazing ocean animals are unique in many ways. It may be tough to tell them apart when catching a glimpse of a fin or nose in the water, but this book offers a closer look, transforming readers into dolphin and porpoise experts in no time.

In this memorable first book, Behind the Dolphin Smile, Richard O'Barry told the inspiring story of his personal transformation from world-famous dolphin trainer (Flipper was his pupil) to dolphin liberator. Now, in To Free a Dolphin, he passionately recounts the dramatic story of his heart-breaking campaign to release captive dolphins back into the wild. With wit and insight he chronicles the extreme opposition he has faced from bureaucrats, major players in the captive-dolphin industry, rival wildlife groups, and well-meaning sentimentalists. He introduces readers to famous show animals he has helped, including Bogie and Bacall of Key Largo. And, most fascinating, he describes his struggles to deprogram and rehabilitate dolphins emotionally scarred from years of captivity--struggles that become battles for the animals' souls.
