n 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.
