Polar Bear

The polar bear  is a carnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean  its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear  A boar  weighs around 350–700 kg  while a sow  is about half that size. Although it is the sister species of the brown bear it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet. Although most polar bears are born on land, they spend most of their time at sea. Their scientific name means "maritime bear", and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present.
The polar bear is classified as a vulnerable species, with eight of the nineteen polar bear subpopulations in decline.For decades, large scale hunting raised international concern for the future of the species but populations rebounded after controls and quotas began to take effect For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of Arctic indigenous peoples, and polar bears remain important in their cultures.
