The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).
Bear habitats are generally forests, though some species can be found in grassland and savana regions, and the polar bear lives in arctic and aquatic habitats. Most bears are 1.2–2 m (4–7 ft) long, plus a 3–20 cm (1–8 in) tail, though the polar bear is 2.2–2.44 m (7–8 ft) long, and some subspecies of brown bear can be up to 2.8 m (9 ...
Overall, it shows that it's unlikely polar bears can adapt to living on land, Derocher said. When polar bears have sea ice, they feast on seals. Not just the seals, but their fat. About 70% of the polar bear diet while on ice is fat, said study co-author Karyn Rode, a USGS wildlife biologist.
[69] [83] The polar bear mainly preys on seals, stalking them from the ice or breaking into their dens. They primarily eat the highly digestible blubber. [84] [81] Large mammalian prey is typically killed with raw strength, including bites and paw swipes, and bears do not display the specialized killing methods of felids and canids. [85]
Researchers found that most of the polar bears are losing weight, about 0.4 to 1.7 kilograms per day.

The polar bear is the most carnivorous species of bear, and its diet primarily consists of ringed (Pusa hispida) and bearded (Erignathus barbatus) seals. [68] Polar bears hunt primarily at the interface between ice, water, and air; they only rarely catch seals on land or in open water. [69]
