What is a polar bear?
Polar bear is a member of a unique bear species that has specially adapted to the Arctic environment. Polar bears can be found throughout the Arctic, in what scientists consider at least 19 different subpopulations. These large animals are considered quite beautiful and majestic and in some regions were used as symbols of Arctic and Arctic culture. Polar bear is also an animal of special interest and interest of scientists, because the polar bears populations are very vulnerable to things like climate change and human intervention. These bears are among the largest predators in the world and reach weights of up to £ 1,300 (600 kilograms), with simplified bodies designed for extremely effective hunting. Polar bears have adapted a number of functions for the Arctic environment, including a thick layer of insulating bubbin, hollow hair, helping to capture warm air next to the skin, and small ears and tails to minimize heat losses. They also have large legs that help distribute itH weight evenly over thin ice and snow.
The distinguishing feature of a polar bear for many people is a classic white coat that has animals right after melting. In fact, the polar bear's hair is not white, as mentioned above; The hair simply licks light in a way that makes it look white. The polar bears can also weather as their hair ages and will be colored, and in captivity, polar bears can green because the eyelashes colonize their hollow hair.
Most polar bears eat seals, mroops, birds and sometimes seaweed and fish. The animals adapted muscular legs to kill their prey with one blow along with a hefty set of teeth for effective consumption. Polar bears live for about 20 years in the wild, and biologists estimate that today there are about 20,000 to 25,000 polar bears who roam after the Arctic.
These animals are considered to be endangered and in some regiThey are listed as endangered species. Polar bears experienced the pressure of the habitat due to reduced icecaps in combination with the expanding human populations in the Arctic. Some polar bears starve because they are unable to find food while others are shot because they are inconvenience for human communities. These unfortunate circumstances have led some biologists to express the alarm over the fate of a polar bear, suggesting that animals could disappear in the wild until the mid -21st century.
