The polar bear or the bounding main/ice behave are the world's largest country predators. They can exist found in the Artic, the U.S. (Alaska), Canada, Russia, Kingdom of denmark (Greenland), and Norway. Each of these countries either banned hunting or established rules for how many polar bears could be hunted within its ain boundaries. These rules aid go along polar bear populations stable. Today, 25,000 to forty,000 polar bears roam the Arctic.

Around the age of four or 5 the female polar deport can start having babies. They usually only have two cubs and they take these babies in a cave they've dug in a large snow drift. They stay there over winter and come up out in spring with the babies.
The babies are much smaller than human babies when they're born. They are the size of a rat and counterbalance little more than a pound. They can grow to full man size in a twelvemonth if they have lots of nutrient.

Male polar bears may grow 10 feet alpine and weigh over 1400 pounds. Females accomplish vii anxiety and weigh 650 pounds. In the wild polar bears live upwards to historic period 25.
Despite what we call back, a polar bear'due south fur is not white. Each hair is a clear hollow tube. Polar bears wait white because each hollow hair reflects the low-cal. On sunny days, it traps the sun's infrared heat and keeps the carry warm at 98 degrees F (when they're resting).
Polar deport fur is oily and water repellent. The hairs don't mat when moisture, allowing the polar bears to easily shake free of h2o and whatever ice that may form afterwards swimming.
Underneath the fur, a polar carry'southward peel is actually black -- the black peel soaks up the sun's rut and helps them stay warm.
Polar bears also have a iv inch layer of fatty underneath their pare. This prevents them from losing any of their estrus. In fact, if you look at a polar bear with an infared camera, they are pretty close to invisible (in other words, they don't give off any heat!)
The smallest foot pad is the front end track
and the larger is the hind track.
Polar bears have broad front paws with slightly webbed toes that aid them swim. They paddle with their front anxiety and steer with their hind feet. Paw pads with rough surfaces aid prevent polar bears from slipping upwards on the water ice.
Polar bears have been known to swim 100 miles (161 kilometers) at a stretch.
Polar bears primarily eat seals. They ofttimes rest silently at a seal'south breathing hole in the ice, waiting for a seal in the water to surface. Once the seal comes upward, the bear volition bound and sink its jagged teeth into the seal's caput.
They have a special liver that allows them to process all of the seal fatty they consume - seals store a lot of vitamin A in their blubber which allows them to survive and grow quickly. A polar bear's liver contains 10 times more vitamin A than whatsoever other animal on earth - their liver has evolved to allow them to process and swallow all of the seal blubber they need to stay alive.
Sometimes the polar bear stalks its casualty. It may meet a seal lying near its breathing hole and slowly move toward it, then charge information technology, biting its head or grabbing information technology with its massive claws. A polar bear may also hunt past swimming below the water ice.
Humans are the polar bears merely predator. Baby polar bears often starve. In fact, 70 percent practise not live to their 3rd birthday. Sometimes seals are hard to notice, especially in the summer when the ice has melted. All across the Arctic, homo is moving in to mine oil and coal and there is less space for the polar bear to live. Oil spills can exist very unsafe. A conduct with oil on its glaze cannot regulate its body temperature properly. If the bear eats the oil while training it could die.
Man made pollution is as well a cause of death. At each stage of the food chain, pollutants become more than concentrated. By the stop when the polar comport eats the seal and information technology could be lethal.
Polar Bears are considered marine mammals -- just like seals, whales and dolphins. Although polar bears are related to the dark-brown bear, they have evolved over fourth dimension to live in cold northern arctic climates. Their population is on the decline and they are considered a "vulnerable" species.

Protecting polar bears isn't but a thing of being nice. Their body is very different than nearly mammals -- they are able to process large amounts of fat (seal blubber) and are able to lose and proceeds large amounts of weight through the year without causing stress wellness problems. Scientists are studying them to see if they can provide a primal to man diseases like diabetes and eye disease!
