The Ursus Maritimus (Ursus maritimus) could be a carnivorous bear whose native vary lies for the most part at intervals the polar circle, encompassing the Arctic Ocean, its encompassing seas and encompassing land lots. it's an outsized bear, about an equivalent size because the omnivorous  Kodiak (Ursus arctos middendorffi).A boar (adult male) weighs around 350–700 weight unit (772–1,543 lb), whereas a sow (adult female) is concerning 0.5 that size. though it's the sister species of the bear, it's evolved to occupy a narrower condition, with several body characteristics tailored for cold temperatures, for moving through snow, ice, and open water, and for searching seals, that structure most of its diet.Though most polar bears area unit born toward land, they pay most of their time on the ocean ice.  Polar bears hunt their prey which is  most popular food of oceanls from the sting of sea ice, typically living off fat reserves once no ocean ice is gift. attributable to their dependence on the ocean ice, polar bears area unit classified as marine mammals.The Ursus Maritimus is found within the polar circle and adjacent land lots as way south as Newfoundland. owing to the absence of human development in its remote surround, it retains a lot of of its original vary than the other surviving carnivore.Whereas they're rare north of 88°, there's proof that they vary all the approach across the Arctic, and as way south as James Bay in Canada. Their southmost vary is close to the boundary between the polar circle and wet continental climate zones. they will sometimes drift wide with the ocean ice, and also there are anecdotal sightings as way south as Berlevåg on the Norwegian solid ground and the Kuril Islands within the ocean of Okhotsk.

Because of expected surround loss caused by temperature change, the Ursus Maritimus is assessed as a vulnerable species, and a minimum of 3 of the 19 Ursus Maritimus subpopulations area unit presently in decline.For many years, large-scale searching raised international concern for the long run of the species, however populations rebounded once controls and quotas began to require impact. For thousands of years, the Ursus Maritimus has been a key figure within the material, spiritual, and cultural lifetime of circumpolar peoples, and polar bears stay necessary in their cultures.
