The Polar bear.

The polar bear is one of eight bear species. Its Latin name is Ursus maritimus, which means “ sea bear”.

The polar bear is the youngest of the eight bear species. Scientists believe the polar bear evolved about year ago from brown bear ancestors.

Polar bears are the world’s largest land predators. They top the foot chain in the Artic, were they dine primarily on seals.

The polar bear’s main prey is the ringed seal. The ringed seal is the most numerous seal the Artic.

Adult Male polar bears weigh from 775 to more than 1,500 pounds. Female are considerably smaller, normally weighing 330 to 550 pounds.

Adult male polar bears measure 6 ½ feet to 10 feet long, excluding the tail. Female measure 5 to 8 feet long, excluding the tail.

Polar bears range throughout the Artic in areas where they can hunt seals at open leads. The 5 “Polar bear nations” where the ice bears are found include the U.S. (Alaska),Canada, Russia, Denmark (Greenland), and Norway.

Polar bears are superbly adapted for survival in the Far North. They are well-insulated against the cold, and they are powerful enough to hunt seals successfully.

Polar bears have a superb sense of smell. They also have excellent hearing and eyesight. These heightened senses are necessary for survival in the charging conditions of the Artic.

Scientist estimate that there are roughly 20,000 to 25,000 polar bears throughout the Artic.

Polar bears are champion swimmers. They have been known to swim more than 60 miles without rest.

Polar bear’s forepaws are partially webbed to assist in swimming. The massive size of the forepaws measures up to 12” in diameter.

The polar bear’s fat layer, which is 3 to 4.5 inches thick, not only protects it from cold the cold but adds to its buoyancy in the water.

The polar bear’s compact ears and small tail help prevent heat loss. When curled up in a ball, they often cover their muzzles to reduce heat loss well.

The marine ice is water of congealed sea. It can have several meters of thickness and one moves over the years. Even though the salts of the sea are not congealed, when the marine ice forms for the first time, congealed concentrated salt water bags are created. These salt water bags can encountered the way to leave the marine ice in few years. During the months of summer, the majority of the marine ice melts to return to form during the months of winter. Portions of ice exist that last throughout all the year
