Walruses deposit most of their body fat into a thick layer of blubber that lies just underneath the skin. This blubber layer insulates the walrus and streamlines its body. It also functions as an energy reserve. During the winter, blubber may account for one third of a walrus' total body mass. For an activity appropriate for grades 4-8, click here.
Walruses seek out physical contact with other walruses.
This helps walruses retain their body heat rather than lose it to the external environment. Physical contact is also indicative of their gregarious nature. All Rights Reserved.
