Polar Bear
Polar bears live for about 25 years and are the largest predator found on land. They are 7 ¼ -8 ¼ feet long and have a tail that is 3-5 inches. Adult females will weigh about ½ that size, so between 150-300kg.
A polar bears body is built for power and swimming. They have flat webbed feet that allow them to swim, and a long neck and narrow skull help propelling the animal in the water.
Their thick, dense coat and a layer of thick blubber that provides heat insulation, and buoyancy allows them to withstand extraordinary lengths of coldness. They have white fur, and black skin to get extra heat. The white fur reflects the light, and then the black skin attracts the light,
They are also quite fast and are able to outrun a caribou in a short distance run, but become tried and are not able to outrun a caribou in a long distance run. The feet of the polar like the Arctic fox have fur on them to stop them from getting cold and to create traction on the ice.
A polar bears will generally be a yellowish shade most of the year due to solar oxidation or staining by oil from seal blubber, which is one of their main food sources. A polar bears coat will only be pure white after they have moltted.
A polar bears diet consist of seals, fish, seabirds, arctic hares, caribou and musk ox, then when summer comes around a polar bear will also eat berries and leaves from the plants found in the tundra.
Polar bears live alone and will travel great distances to other sections of the tundra that belong to other countries or even the other countries themselves. They wander from the Arctic Ocean to southern limits of ice floes and be found in Canada, Russia, Norway, Alaska and Greenland.
The only time polar bears will ever come together is for mating, the gestation period for polar bears is 9 months and a litter of 1-4 cubs are born. The cubs after they are born will stay with their mother for a year, making the female polar bears only able to breed every other year.
