Polar bear walking through wind-blown snow at sunset

Polar bear

Remarkable adaptations allow polar bears to live in the frozen Arctic, but global warming is destroying their habitat and leaving them seriously endangered. Despite being born deaf and blind beneath the snow, cubs eventually grow into the most powerful of all four-legged animals.

Using their incredible sense of smell to track their prey, adult polar bears spend most of their lives alone, wandering over the vast tracts of frozen ice in search of blubber-rich prey such as seals, walruses and even whales. They are also remarkably good swimmers and have been spotted over 60 miles from shore.

About

The polar bear (Ursus maritimus) is a carnivorous bear native largely within the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the world's largest bear, together with the omnivorous Kodiak bear, which is approximately the same size. A boar (adult male) weighs around 350–700 kg (770–1,500 lb), while a sow (adult female) is about half that size. Although it is closely related to 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.[citation needed] 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.
