polar bear kills seal

[156] The treaty allows hunting "by local people using traditional methods". They can occasionally drift widely with the sea ice, and there have been anecdotal sightings as far south as Berlevåg on the Norwegian mainland and the Kuril Islands in the Sea of Okhotsk. [17] In Quebec, the polar bear is referred to as ours blanc ("white bear") or ours polaire ("polar bear"). [33][34][35] One alleged fossil subspecies has been identified: Ursus maritimus tyrannus, which became extinct during the Pleistocene. Polar Bears [106][107], Although seal predation is the primary and an indispensable way of life for most polar bears, when alternatives are present they are quite flexible. [29] However, because neither species can survive long in the other's ecological niche, and because they have different morphology, metabolism, social and feeding behaviours, and other phenotypic characteristics, the two bears are generally classified as separate species. Polar bears sometimes have problems with various skin diseases that may be caused by mites or other parasites. Polar bears consume a wide variety of other wild foods, including muskox (Ovibos moschatus), reindeer (Rangifer tarandus), birds, eggs, rodents, crabs, other crustaceans, fish[108] and other polar bears. The body condition of polar bears has declined during this period; the average weight of lone (and likely pregnant) female polar bears was approximately 290 kg (640 lb) in 1980 and 230 kg (510 lb) in 2004. [37][39] The subpopulations display seasonal fidelity to particular areas, but DNA studies show that they are not reproductively isolated. Research of injury patterns in polar bear forelimbs found injuries to the right forelimb to be more frequent than those to the left, suggesting, perhaps, right-handedness. Some regulations of hunting did exist. [89], With the exception of pregnant females, polar bears are active year-round, although they have a vestigial hibernation induction trigger in their blood. Compared to the Antarctic, where there is no major surface predator, Arctic seals use more breathing holes per individual, appear more restless when hauled out on the ice, and rarely defecate on the ice. These legends reveal a deep respect for the polar bear, which is portrayed as both spiritually powerful and closely akin to humans. [43][211], For the indigenous peoples of the Arctic, polar bears have long played an important cultural and material role. [10], Because of expected habitat loss caused by climate change, the polar bear is classified as a vulnerable species. The bear may lie in wait for several hours. The dental formula is [160], Although the United States government has proposed that polar bears be transferred to Appendix I of CITES, which would ban all international trade in polar bear parts, polar bears currently remain listed under Appendix II. [26] A comparison of the nuclear genome of polar bears with that of brown bears revealed a different pattern, the two forming genetically distinct clades that diverged approximately 603,000 years ago,[27] although the latest research is based on analysis of the complete genomes (rather than just the mitochondria or partial nuclear genomes) of polar and brown bears, and establishes the divergence of polar and brown bears at 400,000 years ago. Thousands of new, high … Seals however nip at polar bears in the water sometimes. [69], The polar bear has an extremely well developed sense of smell, being able to detect seals nearly 1.6 km (1 mi) away and buried under 1 m (3 ft) of snow. Although hauling out may come with the risk of being eaten by a polar bear, it is a required trade-off for being able to survive the summertime heat.
