Polar bear, or polar bear, or polar bear, or sea bear, or oshkuy is a predatory mammal of the bear family, a close relative of the brown bear. The Latin name Ursus maritimus translates as "sea bear".
Instructions
Step 1
The polar bear can be classified as a land mammal only conditionally, since these animals appear on land very rarely, only on the Arctic islands and the sea coast. They spend most of their time wandering on the ice of the Arctic Ocean. The polar bear is superbly adapted to life in the polar seas. Snow storms are frequent in the Arctic. Fleeing from them, polar bears dig depressions in the snowdrifts, lie down in them and leave only after the storm has subsided.
Step 2
The bear seems clumsy due to its size and dimensions, but this is only an appearance. Polar bears can run fast enough, and even swim great. The bear's paw is unique. No deep snow can stop the bear, thanks to its foot size and pillar-like legs, even in comparison with other polar animals, it overcomes any snow and ice obstacles very quickly and dexterously. Cold resistance is simply amazing. In addition to hollow hairs, polar bears also have a subcutaneous layer of fat, which can be up to 10 cm thick in winter. Therefore, a polar bear can easily travel up to 80 km in icy water.
Polar bears hunt pinnipeds, mainly ringed seals, bearded seals and harp seals. They come ashore of the coastal zones of the islands and the mainland, hunt for young walruses, also eat sea waste, carrion, fish, birds and their eggs, less often rodents, berries, mosses and lichens. Pregnant females lie in dens, which they set up on land from October to March-April. In broods, usually 1-3, more often 1-2 cubs. Until the age of two, they remain with the bear. The maximum life span of a polar bear is 25-30 years, rarely more.
Step 3
Today, humans are the greatest threat to the bear population. Along with the retreating ice, which is critical to the survival of the polar bear due to climate change, the drilling of gas and oil wells, increased shipping and the release of industrial chemicals that pollute water are also detrimental to the impact. The polar bear has a relatively low reproduction rate, which means not only a rapid decline in the population, but also not fast enough growth, which helps to maintain the number at the required level. Some experts argue that the polar bear could become extinct in the wild in the next 30 years.
