This text concentrates on ecological and behavioural studies of wild cetaceans, but also considers recent advances in our understanding of the evolutionary history of the order Cetacea, the development of whaling, past and present population sizes for commercially exploited species, zoogeography, breeding biology, migration patterns and conservation problems. Drawing on a considerable amount of unpublished and unique data, this book will be of interest to the informed naturalist as well as the professional biologist.
