Life cycle of polar bear: 

Polar bears mate every other year in mid-summer. The female digs a den in the snow and stays there for nine months until her young are born. She has between one and four cubs. The cubs are hairless and toothless when they are born and are about the size of a chipmunk. The cubs stay with their mother for one to two years.

The unique of polar bear

An interesting feature of the coat is that it appears black when photographed with ultraviolet light. A number of people have suggested that this is because the hairs channel the light to the black skin of the bear to help it stay warm during the cold, sunless winters. Measurements show, however, that the hairs strongly absorb violet and ultraviolet rays. This is why the polar bear's pelt often appears yellow. More colorful polar bears have occasionally been reported. In February 2004, two polar bears in the Singapore Zoo appeared to turn green as a result of algae growing in their hollow hair tubes. A zoo spokesman said that the algae had formed as a result of Singapore's hot and humid conditions. The bears were washed in a peroxide blonde solution to restore their expected color were cured by washing the algae away in a salt solution.

Additional info:

The polar bear's white fur helps camouflage it in its polar environment. The polar bear has two layers of fur, a soft under coat and an outer coat of guard hairs. The guard hairs are hollow and help the polar bear float.

The polar bear has fur on the soles of its feet that helps protect it from the cold and ice and prevents the polar bear from sliding on the ice. The polar also has some webbing between its toes that help it paddle in the water.

Its long neck helps the polar bear keep its head above water when it is swimming. Male polar bears are larger than females. They can weigh as much as 1,600 pounds.
