Exploring the World of Seals and Walruses - Softcover

Inhaltsangabe

The lifestyle of the seals that entertain at marine parks has little to do with how seals, sea lions and walruses actually survive in the wild. Exploring the World of Seals and Walruses explains how these pinnipeds have adapted to live in two habitats, on land and in water. This ancient group of sea mammals comes in wildly different sizes, from the 50 kilo ringed seal to the 3-tonne elephant seal, and the range of their behaviours varies just as widely. With their streamlined bodies, insulating blubber or fur, flippers where other animals have limbs and long necks, these marine mammals are built to navigate the water in search of food, yet most of them court, mate and give birth on land. How do seals and walruses regulate their body temperature? How do they see their prey and predators in the dim underwater light? What are the effects of massive oil spills on the survival of these species that have inhabited Earth for millions of years? Exploring the World of Seals and Walruses provides these answers and many more.
