Thank you for supporting the creative commons movement !! The polar bear is a predatory species from the family of bears. He lives in the northern polar regions and is closely related to the brown bear related. He is next to the Kamtschatka and the Kodiak bear as the largest land-living predator on the planet. Adult male polar bears reach an average head-body length of 2.40 to 2.60 meters, in some cases even up to 3.40 meters; shoulder height is up to 1.60 meters. The weight varies between 300 and 800 kg. When Body polar bears differ from other bear species with a long neck and a relatively small, flatter head. In contrast to the closely related brown bears they lack the muscle mountain at neck. The eyes are relatively small. The ears are erect and forward round shaped. Like most bears polar bears have 42 teeth, and like all bears, they are plantigrade. Their front legs are long and strong; the large front paws are paddle shaped and webbed, enabling fast swimming. On the muscular hind legs, the polar bear can raise the maximum height; the hind legs are used for swimming as a rudder. Polar bears are exclusively in the Arctic today and found circumpolar, ie in the Arctic region around the North Pole. Most high arctic polar bears keep throughout the year on the coasts or on the sea ice in order to hunt seals there. They prefer doing areas where the ice remains by wind and ocean currents into motion and is torn again and again, making ice-free spots result. In summer, polar bears mainly stick to the southern edges of the sea ice. For a long time it was thought, polar bears are marked hikers, the spacious follow the movement of the ice around the North Pole. Recent observations have shown, however, that there are a greater number sedentary populations. These include, for example, the polar bears of Wapusk National Park and the Ukkusiksalik National Park. The northernmost latitude, were observed on the polar bear, is 88 °, the most south-occurring animals live along the Hudson Bay and the Northwest Coast of slightly further southeast, James Bay on. Regularly polar bears are also occasionally Newfoundland and Iceland sighted. Polar bears are active during the day and especially during the first few days in third movement. Approximately 29 percent of their time to take hiking and swimming to complete and only 5 percent are attributable to the hunting and eating. About 66 percent of their time they spend sleeping, however, dormant or lurking for prey. The suckling of the young are predominantly at lunchtime. Polar bears are like all bears solitary, except for mothers with their young. The hunting ground of a polar bear extends via a radius of about 150 kilometers, but the animals show no very territorial and the areas overlap to a large extent. Polar bears are very good swimmers, but usually do not hunt in the water for prey. Floating they can travel more than five miles an hour. Dives two minutes prepare them no difficulty; the diving depth but rarely is more than two meters. On land, polar bears wander for hours over long distances. Of all species of bears Polar bears need most pronounced on meat supply. You are at the top of the natural arctic food chain, so are top predators. The main component of their diet make seals, mainly on ringed seals, but also Beard and harp seals, hooded seals as well as young or weakened walruses. In exceptional cases, polar bears may also prey on adult walruses. In open water it is hardly possible polar bears to prey on seals. During the winter, however, offer to pack ice fields of crevasses best hunting conditions. Polar bears can track seals with their sense of smell in more than one kilometer or one-meter-thick ice or snow layers. They usually prey on seals at their breathing holes. Camouflaged by his bright fur of the polar bear has adapted to the environment and is not easily perceived by the prey below the water level. Well-fed polar bears eat the freshly killed prey only skin and fat, the rest remains lie. About the prey remains make weaker bears or arctic foxes ago, but also carrion-eating birds such as gulls. Many arctic foxes have really specialized to recycle leftover food of polar bears. Thank you for supporting the creative commons movement !!
