Summary: This book explores the lives of the world's largest living mammals. Drawing on the latest scientific research, Whales describes these incredible animals' evolution from terrestrial to marine mammals, their life cycle, diversity and distribution, and the ecosystems of which they are a part. Whales highlights the many extraordinary aspects of these intelligent and social creatures, including the complex vocalizations they use to communicate over vast distances. Philip Hammond, Sonja Heinrich, Sascha Hooker, and Peter Tyack investigate the role of whales in human culture, from whaling to whale watching, and emphasize how scientists monitor the current threats to whales and the methods they use to conserve their future.
