How did the elephant seal survive being driven to the brink of extinction in the nineteenth century? What variables determine the lifetime reproductive success of individual seals? How have elephant seals adapted to tolerate remarkable physiological extremes of nutrition, temperature, asphyxia, and pressure? Answering these questions and many more, this book is the result of the author's 50-year study of elephant seals. The chapters cover a broad range of topics including diving, feeding, migration and reproductive behavior, yielding fundamental information on general biological principles, the operation of natural selection, the evolution of social behavior, the formation of vocal dialects, colony development, and population changes over time. The book will be a valuable resource for graduate students and researchers of marine mammal behavior and reproductive life history as well as for amateur naturalists interested in these fascinating animals.

'Every person interested in enigmatic animals will enjoy reading this book that tells the story of the Northern Elephant Seal. This animal knows the Pacific in its width and depth and yet returns to a spot on the beach every year to reproduce in a crowded colony fiercely competing with its neighbours to achieve maximal fitness. With his decades-long dedication to the study of elephant seals, Le Boeuf presents a wonderful broad picture of this amazing animal and unravels the secrets of its natural history.'
