Polar Bears

Polar Bears are found in Canada, Alaska, Russia and Norway. They are good swimmers and are known to swim for days with a speed of 10 kilometers an hour. Under water they can keep their breath for up to 2 minutes. They can grow up to 9 feet tall and weigh about 1,763 lbs (800 kilos.) On land they can reach a speed of 40 kilometers an hour. They are not very good hunters. When the mother polar bear is pregnant, she digs a hole in the snow, big enough for her and her babies. She keeps them in there until the spring. There are about 26,000 polar bears in existence, but their number is dwindling fast, mostly because of the climactic change in the North Pole and surroundings.
