Polar Bears (Ursus maritimus) are known to uncommonly move smoothly extensively with the sea ice, and there have been anecdotal sightings as far south as Berlevag on the Norwegian mainland and the Kuril Islands in the Sea of Okhotsk. It is difficult to guess a comprehensive population of Polar Bears (Ursus maritimus) as much of the range has been poorly studied, however biologists use a working estimate of about 20,000 to 25,000 Polar Bears (Ursus maritimus) worldwide.
Polar bears (Ursus maritimus) are over and over again regarded as a marine mammal. The reason as to why Polar bears (Ursus maritimus) are regarded as marine animals is only because it spends many months of the year at sea. The preferred habitat of Polar Bears (Ursus maritimus) is the annual sea ice covering the waters over the continental shelf and the Arctic interisland archipelagos. These areas, known as the Arctic ring of life, have high biological productivity in comparison to the deep waters of the high Arctic. The polar bears (Ursus maritimus) tend to frequent areas where sea ice meets water, such as polynyas and leads temporary stretches of open water in Arctic ice, to hunt the seals that make up most of its diet. Polar bears (Ursus maritimus) are therefore found primarily along the border of the polar ice pack, rather than in the Polar Basin close to the North Pole where the density of seals is near to the ground.

Polar bears (Ursus maritimus) are generally found throughout Arctic Circle and adjacent land masses. This is the place where Polar Bears (Ursus maritimus) are largely known to live. Due to the absence of human development in its remote habitat, Polar Bears (Ursus maritimus) are known to retain more of its original range than any other extant carnivore. While they are rare north of 88 degree, there is evidence that they range all the way across the Arctic, and as far south as James Bay in Canada.
