Agreement on the Conservation of Polar Bears Biologists estimate there are roughly 20,000 to 25,000 polar bears. They base this estimate on the best available information, combined with expert opinions on those populations that lack current data. About 60% of the world's polar bears live within or are shared by Canada. Polar bears are also found in the U.S. (Alaska), Russia, Greenland, and Norway (Svalbard).

- Polar bears are found across the Arctic. They are most abundant in areas with annual sea ice and productive ringed seal populations. There are five nations with polar bears: U.S. (Alaska), Canada, Russia, Greenland (Kingdom of Denmark), and Norway (Svalbard). Polar bears do not live in Antarctica.n the wild, polar bears live an average 15 to 18 years, although biologists have tagged a few bears in their early 30s. In captivity, some long-lived bears reach their mid-to late 30s. Debby, a captive bear in Canada, lived to be 42.

Polar Bear Swim The Vancouver Polar Bear Swim Club is one of the largest and oldest Polar Bear Clubs in the world. Its initial swim was in 1920 when a small number of hardy swimmers took the plunge into English Bay on New Year's Day. Led by their founder, Peter Pantages, the swim has grown from around 10 swimmers in that year to the new record of 2,550 official entries set in 2014.

Polar bear The polar bear (Ursus maritimus) 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 (Ursus arctos middendorffi).he polar bear also hunts by stalking seals resting on the ice: Upon spotting a seal, it walks to within 90 m (100 yd), and then crouches. If the seal does not notice, the bear creeps to within 9 to 12 m (30 to 40 ft) of the seal and then suddenly rushes forth to attack.
