North Pole is the northern end of the Earth spin axis, that is the point of 90 ° north latitude. Arctic near the North Pole is latitude 66 ° 34 'area within the Arctic Circle. The frozen Arctic Ocean is a vast ocean, surrounded by numerous islands and coastal areas of northern North America and Asia. Cold waters of the iceberg from the Arctic Ocean flows carrying the Atlantic and Pacific. Arctic cold climate throughout the year. Winter, the sun is always below the horizon, the sea ice completely frozen. Summer, the temperature rose to above freezing, melting the edge of the Arctic Ocean, the sun for weeks are hanging in the sky. Arctic Ocean are rich in fish and plankton,
This summer here, millions of seabirds nesting provides a rich source of food, and also the seals, whales and other marine animals.Most areas around the Arctic Ocean are flat, no trees. Winter, frozen earth, the ground covered with thick snow. Summer snow melt, thaw the surface soil, plants grow and blossom, as the reindeer and musk oxen and other animals with food. Meanwhile, wolves and polar bears and other predators also depend on other animals to survive predation. Arctic is the world's most sparsely populated areas. Since centuries, the Inuit (formerly Eskimo) sound reproduction from generation to generation here. Recently, the discovery of oil here, so many people came to work here from the south.
The most representative and symbolic animal is the Arctic polar bears.
As the name suggests, polar bears live in the Arctic. Their home in the Arctic ice and the surrounding islands, as well as the adjacent mainland near the coast, was the circumpolar distribution of basic. They generally will not go deep into more northern areas, where the ice is too thick, and even their main prey - seals can not break the ice out, no food, polar bears will naturally not take the risk.
Polar bears living there were classified into six species: Russia Wrangel Island - Alaska Western populations; population in northern Alaska; the Canadian Arctic archipelago population; Greenland population; Norway, Svalbard - 俄罗斯法兰兹 Joseph Island population and to central populations in northern Siberia.
Polar bear in the bear family animal family are genuine carnivores, they feed seals, especially ringed seals, will also prey bearded seal, harp seal, crown seals. In addition, they also capture the walrus, beluga whales, seabirds, fish, small mammals, sometimes cleaning the carrion. , And other bear species have different, they are not eating the food will not hide after the eat, etc. (This is one great convenience to other animals, such as Arctic fox lazy or similar), even after the fat from time to time to enjoy complete to walk away, know that for them, high-calorie fat is more important than the meat,
Because they need to maintain a warm layer of fat used, also need to store energy when food shortages. Polar bears are not vegetarians do not stick a little, occasionally in the summer they eat berries or plant roots, although they are not high in terms of nutritional value.
Polar bears are excellent swimmers, so that once people believe that marine animals, it is not only the Latin name U. maritimus means "sea" Bear. Polar bears in their lives most of the time (66.6%) were in the "static" state, such as sleeping, lying down resting, or waiting for prey. The remaining approximately 29.1% of the time walking or swimming in the land, 1.2% of the time in the attack prey, what is left is to basically enjoy delicious. There are two kinds polar bear hunting mode, the most common is the "passive" method. They will advance to find the ice seal's breathing hole
And highly endurance waiting several hours in the next. Wait until the seals appear, they will launch a surprise attack, with sharp claws hook to drag the seal up from the breathing hole. If the seals on shore, they would hide in places where seals eye can not see, and then crept to come crawling to launch onslaught. Another model is to sneak into the ice directly under seal until close to the shore before the attack, so the advantage is a direct escape route cut off the seals. Satiate, the polar bears will carefully clean up the hair, the food residue of blood are cleaned.
Starving polar bears turn to cannibali *** 。
New pictures show that polar bears are beginning to cannibalise each other as global warming destroys its hunting grounds。
Polarbears usually subsist on seals, which they hunt from a platform of seaice. But the melting of sea ice as a result of rising globaltemperatures has made it more difficult for polar bears to hunt sealsat sea, confining the bears to land。
Drowning is also more mon as bears are forced to swim further out to sea to find food。
Theimages add to the evidence that polar bears are increasingly huntingeach other for food in their desperation to survive.Scientists say theyare aware of eight cases so far this year。
Recent *** ysis by the US Geological Survey and World Conservation Union foundthat o-thirds of the 20,000 to 25,000 polar bears in the world couldbe lost in the next 50 years as warming temperatures melt the ice。
Withoutthe sea ice habitat, the polar bear will not survive in the long term.There are other threats, such as oil and gas drilling, shipping andtoxins, but they pale in parison to climate change and the loss ofthe sea ice。

The polar bear is the world's largest land carnivore, also known as polar bear, naive. Skin is black, because the hair is usually transparent so that the appearance of white, there are yellow and other colors, great size, ferocity.
Polar bears considerable human vision and hearing, but their sense of smell is very sensitive, is seven times the dog; when running the fastest speed of up to 60km / h, 1.5 times the world 100 meters champion. As global temperatures rise, gradually began to melt the Arctic ice floes, polar bears former home has been a certain degree of damage is likely to become extinct in the near future, human needs protection.
Unlike Black and Grizzly bears, which are primarily nocturnal, the Polar Bear may be active at any time of the day or year, searching for prey on long summer days and sometimes on long winter nights. Adaptations to its Arctic habitat include its fur color, which blends with the snowy environment and so provides useful camouflage for capturing prey; its large size, which helps maintain body temperature by reducing surface-heat loss; and its furred feet, which insulate against cold and provide traction on icy surfaces. Because the hairs of its waterproof coat are hollow, they are especially insulating and increase the bear's buoyancy when swimming. An excellent swimmer, it paddles at about 6 1/2 mph (10 km/h) with the front feet only, hindfeet trailing-a trait unique among four-footed land animals-and can remain submerged for about two minutes. While swimming or treading water, it stretches its long neck for a better view, as it does on land. Owing to the scarcity of plants in its icy habitat, the Polar Bear is the most carnivorous North American bear, with canine teeth larger and molariform teeth sharper than those of other bears. An acute sense of smell enables the Polar Bear to locate prey even when it is hidden by snow drifts or ice. It stalks young seals and Walruses, and sometimes adult seals, often by swimming underwater to their ice floes. While hair seals are its staple, it also feeds on fish, birds, bird eggs, small mammals, dead animals (including whales), shellfish, crabs, starfish, and mushrooms, grasses, berries, and algae, when available. The Polar Bear hollows out a winter den in a protected snowbank, where it retires in a lethargic condition. Females den from November to March, during which time they give birth. Males den for much shorter periods, usually from late November to late January, but may be abroad occasionally at any time of the year. Cubs remain with their mother about a year and a half, denning with her the winter after their birth. The lowlands of Hudson Bay and James Bay, one of the world's largest denning areas for Polar Bears, is the only known region where Polar Bears den in earth rather than in snow. They excavate caves in lake and stream banks and peat hummocks by digging down to the permafrost. This area is unusually far south for the species, and it is believed that they use the permafrost dens again in summer to cool off. No large denning areas have yet been found in Alaska; some Polar Bears in that region may winter in Siberia, drifting across to Alaska on ice floes in spring. Polar Bears are a source of food and hides for Native Americans. 答案补充 英文好自己从中间找到答案!
