Male polar bears may grow 10 anxiety tall and counterbalance over 1400 pounds. Females reach vii feet and weigh 650 pounds. In the wild polar bears live up to historic period 25.
Despite what we think, a polar behave's fur is not white. Each hair is a clear hollow tube. Polar bears look white because each hollow hair reflects the light. On sunny days, it traps the dominicus's infrared estrus and keeps the behave warm at 98 degrees F (when they're resting).
Polar bear fur is oily and water repellent. The hairs don't mat when wet, allowing the polar bears to easily shake free of water and any ice that may course after pond.
Underneath the fur, a polar bear's pare is actually black -- the black skin soaks up the sunday's heat and helps them stay warm.
Polar bears also accept a iv inch layer of fat underneath their peel. This prevents them from losing any of their rut. In fact, if you expect at a polar comport with an infared camera, they are pretty close to invisible (in other words, they don't requite off any estrus!)
The smallest foot pad is the front end track
and the larger is the hind track.
Polar bears take wide front paws with slightly webbed toes that assist them swim. They paddle with their front feet and steer with their hind feet. Hand pads with rough surfaces help forestall polar bears from slipping up on the ice.
Polar bears have been known to swim 100 miles (161 kilometers) at a stretch.
Polar bears primarily eat seals. They oft residual silently at a seal's animate hole in the ice, waiting for a seal in the h2o to surface. In one case the seal comes up, the conduct will spring and sink its jagged teeth into the seal's head.
They have a special liver that allows them to procedure all of the seal fatty they swallow - seals store a lot of vitamin A in their blubber which allows them to survive and abound speedily. A polar bear's liver contains x times more vitamin A than whatsoever other animal on globe - their liver has evolved to let them to procedure and eat all of the seal blubber they need to stay alive.
Sometimes the polar conduct stalks its prey. It may come across a seal lying near its animate hole and slowly motion toward it, then accuse it, biting its caput or grabbing information technology with its massive claws. A polar carry may also hunt by pond below the ice.
Humans are the polar bears only predator. Baby polar bears often starve. In fact, seventy percent do not live to their third birthday. Sometimes seals are hard to find, especially in the summer when the ice has melted. All beyond the Arctic, man is moving in to mine oil and coal and there is less infinite for the polar comport to live. Oil spills tin can exist very dangerous. A bear with oil on its coat cannot regulate its body temperature properly. If the bear eats the oil while preparation it could dice.
Homo made pollution is also a cause of death. At each stage of the food chain, pollutants become more concentrated. By the terminate when the polar carry eats the seal and it could be lethal.
Polar Bears are considered marine mammals -- but like seals, whales and dolphins. Although polar bears are related to the brown bear, they have evolved over time to live in cold northern arctic climates. Their population is on the reject and they are considered a "vulnerable" species.

Protecting polar bears isn't just a thing of existence dainty. Their body is very different than most mammals -- they are able to process large amounts of fat (seal blubber) and are able to lose and gain large amounts of weight through the yr without causing stress health problems. Scientists are studying them to run into if they can provide a key to man diseases like diabetes and heart illness!
