Polar bears vary with size and weight between gender and age. The average male polar bear is 8-9 feet long and weighs from 550-1,320 pounds. The average female polar bear is 6-7 feet long and weighs from 200-700 pounds. For both males and females they live about 25-30 years long.

Life Cycle:
Polar bears will mate every other year in mid-summer, which is when their life cycle starts. In a den she dug, the female will hibernate for nine moths until she gives birth, to usually between one and four cubs. These cubs are hairless and toothless, and will stay with their mother for about 2 years to learn survival skills of the north.
Habitat:
Polar bears are found in the Arctic, the most important ones for polar bears include the edges of pack ice where currents and wind interact. Certain areas like this are where polar bears find the most seal. Major abiotic factors that affect polar bears are water snow, and the cold. They have grown long, thick fur, and have a thick layer of blubber underneath the skin, while having small ears and tails, which reduce the loss of cold through those areas. Since polar bears are adapted for a life of swimming, their nostrils can close, to prevent water from entering them. Their fur also flattens when swimming which forms a waterproof barrier. One biotic factor is fish. Fish provides nutrients for them and is their main food source.
