Animal Adaptation to Environment

Polar Bears

Polar bears are well adapted to their arctic surroundings. Their thick winter coats, with glossy hair, dense under fur, and thick layer of fat beneath their skin protect them against the cold. The glossy hairs also shed water easily, so that after a swim the polar bear can shake itself like a dog to decrease chilling and to dry itself fairly quickly. The polar bears hair is translucent and reflects the heat from the sun down to the base of the hair, where it is taken in by the extremely absorbent black skin.

The white colour of the polar bear also serves as camouflage. Polar bears are clever in their use of cover. This aids both their hunting of seals and their own escape from human hunters. The paws of the bears feet have small bumps and cavities that act like suction cups which help to keep them from slipping on the ice.

Probably the most significant adaptation of polar bears to the uncertainties of food availability in the Arctic is their ability to slow down their metabolism, in order to conserve energy after 7–10 days of not being able to feed, until food becomes available again.

The thick layer of fat on the seal is called blubber. The blubber is an extremely good insulator as it keeps much needed heat trapped inside for much longer. It has oily hairs protruding from the skin which lay horizontally creating an extra layer on the seal.

Its skin is dark which helps absorb sun light.
