Polar bears live in cold climates where they can survive based on their fur. They can be found by the water based on their main prey (seals). They are found in Canada, the U.S, Greenland, Russia, and Norway. Polar bears live in the Arctic and in four different sea ice regions across the Arctic (Where do Polar Bears Live)


Polar bears are known on how slow they walk. They are able to gallop as fast as a horse over short distances, but they don't usually prefer to run like a horse. Female polar bears will walk more slowly than male polar bears because the female polar bears have their cubs to walk with. Polar bears expend more than twice the energy of most other mammals. Polar bears can run as fast as 40 kilometers per hour, but only for short distances. Younger bears are the best runners, they can cover two kilometers without stopping. Polar bears are natural sprinters and are very dangerous over short distances. (Polar Bear Movement)

Body Covering

Polar bears fur is not actually white. It just looks like it has white fur Polar bears fur looks the whitest when they are clean and are in the sun in a open field. Polar bears have black skin and the white fur to cover it. On land, polar bears fur coat is very thick. It prevents heat loss and then the polar bears will not get cold. (Polar Bear Characteristics)

Polar bears mainly feed on ringed seals or bearded seals. They also eat harp seals, hooded seals, and scavenge on carcasses of beluga whales, walruses, narwhals, and bowhead whales. When polar bears can not find food they will eat just about anything such as reindeer, small rodents, seabirds, waterfowl, fish, eggs, kelp, berries, and human garbage. Polar bears don't always eat the entire meal. Polar bears don't usually kill humans. Polar bears are smart and are patient when they are hunting for seals, they even sometimes wait in a breathing hole for a seal to com up and then they strike, or they sneak up on a seal when they are taking naps and then they have their meal.

Mating takes place for polar bears on the sea ice from April until late June. Polar bears give birth to cubs about two months after they enter the maternity den. For 20 months polar bear cubs depend on their mother for survival. Sometimes cubs have to find food for themselves. (Polar Bear Mating)

Polar bears are adapted to fiercely cold weather. Compact ears and a small tail help prevent heat loss. Polar bears will sometimes dig shelter pits in snow banks and curl up into a ball to keep warm if the weather gets too cold. Polar bears have more problems with overheating than they do with the cold. Polar bears can quickly overheat when they run. The polar bear lives his life closely to the sea because they are sometimes known as the sea bear. ( Polar Bear Adaptions)
