Polar Bears Northern Arctic Rulers
Polar Bears Northe Arctic Rulers The Polar Bears (Thalarctos maritimus) live in Arctic regions to the north, near rivers, where their main food source, seals. These bears are huge with adults at 7-8? The feet in height and up to 1,600 pounds. Polar bears are white to creamy white all year round to their excellent camouflage against the Arctic snow when hunting. Together with the Arctic fox, the polar bear is the most northerly located land mammal on earth. Unlike other species of bears, polar bears have longer necks and smaller heads, which seem to be more streamlined. Despite their large size, are incredibly fast to a position up to 25 mph. Speed of this type, a polar bear can Outrun a reindeer. They are also excellent swimmers will be able to swim at about 3 miles per hour but for considerable distances. In winter, spending most of their time on the ice hunting seals. Polar bears have rough, leather pads on the bottom of the feet footholds to keep the ice on slippery surfaces. Their adaptation to the cold Arctic waters is even more impressive. Their thick layers of fur traps a deep layer of insulating air around their bodies. An inner layer of dog fur is so compact that it is almost impossible to wet. An outer layer of the mat long hair in water, which is another layer on the inner layer. After a polar bear leaves the water, he just shakes his body, which results in the majority of water thrown from the right with almost dry. The skins of protection to ensure that polar bears skin is kept dry most of the time, although in Arctic waters. Polar bears hunt seals by waiting lists for the seals to come through holes in the ice to breathe. They also stalk their prey using their white camouflage abilities against the mounds of ice. Sometimes polar bears have been known to crawl on their bellies until they are close enough to run their prey, especially if the coverage is not available. Besides seals, polar bears eat arctic foxes, birds, baby walruses and even though men are very hungry. Men and women remain apart for most of the 'year, except during the summer mating season. Women tend to breed only every two years and when they do, usually 1-4 children were bo in March-April. The Polar Bear boys stay with their mothers for 1 to 2 years. The lives of polar bears can be up to 34 years. The Inuit hunt polar bears for their fat, tendons and fur. Scientists say that climate change, the ice in the Arctic, the disturbances in the polar bear feeding and migration. There are estimates of about 22,000 to 25,000 polar bears in the world, with 60 per cent to the Canadian Arctic. Their populations are probably stable now, but some speculate that the species is in danger. Some are of the opinion that if climate change on its existing all over the world and if hunting is not adequately controlled, polar bears could be threatened with extinction in about 100 years. There is currently a wide debate on the annual adjustment of allowances for hunting polar bears, even for Inuit hunters, to further contribute to the protection of these great bears. Polar bears are the most popular symbol of the Arctic north with representations of everything from soft-drink advertising to corporate logos of businesses in the North, including the airlines of the Canadian North. Nunavut has also cut their plate in the shape of a polar bear. Tourists can see polar bears in nature through unique visits on specially designed tundra buggies in Churchill, Manitoba in Canada. It is also not surprising that polar bears are among the most popular after Inuit sculptures. Polar bears are definitely the ruler of the Arctic north.
