Dugongs, Whales, Dolphins and Seals A Guide to the Sea Mammals of Australasia

Until quite recently, the undersea lives of the sea mammals of Australasia have been a mystery. This book unravels the secrets of the dugongs, whales, dolphins and seals that inhabit the oceans around Australia, New Zealand and Antarctica.
Detailed descriptions of each species are supplemented by superb illustrations, colour photographs and informative distribution maps. An examination of the origins of the different sea mammals provides insight into how they came into the region and how they have adapted to meet the challenges of living in the ocean, in addition to the continuing conflict between their welfare and human habitation and development.
