Download or read book Elephant Seals written by Burney J. Le Boeuf and published by Univ of California Press. This book was released on 1994-01-01 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The largest of all seals, elephant seals rank among the most impressive of marine mammals. They are renowned for their spectacular recovery from near-extinction at the end of the nineteenth century when seal hunters nearly eliminated the entire northern species. No other vertebrate has come so close to extinction and made such a complete recovery. The physiological extremes that elephant seals can tolerate are also remarkable: females fast for a month while lactating, and the largest breeding males fast for over one hundred days during the breeding seasons, at which times both sexes lose forty percent of their body weight. Elephant seals dive constantly during their long foraging migrations, spending more time under water than most whales and diving deeper and longer than any other marine mammal. This first book-length discussion of elephant seals brings together worldwide expertise from scientists who describe and debate recent research, including the history and status of various populations, their life-history tactics, and other findings obtained with the help of modern microcomputer diving instruments attached to free-ranging seals. Essential for all marine mammalogists for its information and its methodological innovations, Elephant Seals will also illuminate current debates about species extinctions and possible means of preventing them.

Available in PDF, EPUB and Kindle. Book excerpt: Southern elephant seals are sometimes called "sea elephants." Why? An adult male seal has a nose that, when filled with air, looks like an elephant's trunk! These big seals, weighing in at more than 8,000 pounds (3,629 kg), look like elephants in other ways, too. Both are large animals and many of the seals, like elephants, are gray. In Southern Elephant Seal: The Biggest Seal in the World, large color photos and grade-appropriate text will engage young readers as they learn about the natural habitat, physical characteristics, diet, life cycle, and behavior of this super-sized seal. A comparison diagram is also included to show readers the animal in relation to a familiar object.

Download or read book Elephant Seals written by Bernard J. Le Boeuf and published by Cambridge University Press. This book was released on 2021-10-07 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Return from Extinction written by Linda L. Richards and published by Orca Book Publishers. This book was released on 2020-10-13 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Less than 100 years ago, the northern elephant seal was thought to be extinct. Today more than 250,000 elephant seals swim in the Pacific Ocean from Alaska to Mexico. In Return from Extinction: The Triumph of the Elephant Seal Linda L. Richards tells the story of their dramatic recovery. Elephant seals were hunted to near extinction for their precious oil before the Mexican government stepped in to protect them. Many people thought it was too late. Even though the life of the elephant seal is difficult and only 20 percent of pups born will make it to adulthood, the species adapted and came back from the brink. They are a true conservation success story.
