|Polar bear at the Berlin Zoo, Germany.|
The polar bear is native to the Arctic Ocean and its surrounding seas. It is the world's largest carnivore found on land. An adult male weighs around 400–680 kg, while an adult female is about half that size. Although it is closely related to the brown bear, it has evolved to occupy a narrow ecological niche. Many of its bodily characteristics are 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, hence its name meaning "maritime bear", and can hunt consistently only from sea ice, spending much of the year on the frozen sea.
