Adaptations in Polar Bear

The polar bear is a large, white bear which lives in north polar regions of the earth. The polar bear feeds mainly on fish and seal.

1) Polar bear has white colour which matches with its surroundings: Due to white colour, polar bear is not visible easily in the snowy white background and hence its prey is unable to see it. This adaptation (of white colour) helps the polar bear to catch its prey. The white colour of polar bear also protects it from its predators.

2) Polar bear has two thick layers of fur on its body: This fur protects the polar bear from extreme cold by preventing the loss of heat from its body. Thus, the two thick layers of fur keep the polar bear warm in extremely cold climate. The polar bear has also fur on its feet and toes. This protects it from cold when it walks on snow and ice.

3) Polar bear has a thick layer of fat under its skin: This layer of fat insulates the body of polar bear against heat loss and keeps it warm in cold climate.

4) Polar bear has a rounded body and small ears to keep the body surface area to a minimum.This reduces the heat loss from the body of polar bear.

5) Polar bear has big feet (or big paws) to spread the weight of its body on snow which prevent it from sinking into snow and make it walk on snow easily. Polar bear has long, curved and sharp claws which help it to walk and run on slippery ice.

6) Polar bear is a good swimmer: The big feet (or big paws) help the polar bear to swim well. Being a fast swimmer helps the polar bear to catch its prey (like seal) in water very easily.

7) Polar bear has a very strong sense of smell: The very strong sense of smell helps the polar bear in locating and catching its prey for food.
