Covers that fascinating group of animals whose evolution into their present forms and lifestyles seems almost contradictory. While seals, sea lions and walruses are mammals, their habitat is an aquatic one, their limbs fully adapted for swimming rather than land locomotion. This book describes and illustrates the various families of the order Pinnipedia -- fur seals, sea lions, walruses and the phocid seals. Evolution, classification, distribution, life-cycles, zoology and their current status and future are all discussed, as well as the question of their relationship with humans. Examines controversial topics such as conflicts between seals and fishing and culling and the fur trade. 100 color photos, detailed diagrams and maps. Comprehensive!
