Fur seals, sea lions, walruses and the phocid seals are all described and illustrated. Evolution, classification, distribution, life-cycles, zoology and their current status and future are all fully discussed. Adopts a professional and unemotional approach, examining topics such as culling and the fur trade, placing these romanticized creatures in a sensible context in interactions with humans. Presents a clear view and understanding of their natural history, enhanced by some 100 colour photographs, detailed diagrams and maps.
