Polar white bear.

The largest mammal in the world is the polar bear. In order to survive in the cold climate of the polar region, Kundrat has put a 10 cm thick layer of fat on his body. This bear weighs 650 kilograms. It is 11 feet tall when erect. It lives on icebergs floating in the cold sea waters of the polar regions. Polar bears are skilled swimmers. They have thick hair so they can run easily on ice. He can run at a speed of 25 km when needed. This bear hunts large fish.

Nature has arranged many miracles in the white bear to survive in the cold region. Its ears are kept very small so that body heat does not escape. So he can hear less. This in turn has made his nose more powerful. From far away he can smell the flesh. Its fur is white. But the skin is black so it absorbs heat. Surprisingly, his thin white hair is hollow and through it the heat of sunlight reaches his body. A white bear's fur is soft and beautiful. Poachers hunt it for its skin.
