Bears are mammals of the family Ursidae. Common characteristics of modern bears include a large body with stocky legs, a long snout, shaggy hair, plantigrade paws with five nonretractile claws, and a short tail. While the polar bear is mostly carnivorous and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous, with largely varied diets including both plants and animals. With the exceptions of courting individuals and mothers with their young, bears are typically solitary animals.

Polar Bears

Polar bears are found in the circumpolar Arctic. The majority of polar bears are found near land masses around the edges of the polar basin. They prefer a sea ice habitat with leads or water channels through the ice, and polynyas which are areas of water surrounded by ice.

Some polar bears follow the ice pack year round, migrating as the ice recedes and advances. Polar bears have a thick layer of fat under their skin and thick fur coats that keep them warm in the cold.

Polar bears live in the North pole their yellow fur acts as camouflage so they can sneak up on walrus and seal without being seen.

Polar bears have wide and powerful feet, they have scooped claws which they use for digging. The thick pads on their feet provide traction on the snow and ice of the arctic. Polar Bears have large partially webbed paws, for paddling in the Arctic waters. The paw has a thick black pad with small bumps that helps with traction on the ice. Polar Bears have a dense woolly coat with two layers. The polar bearís fur is oily which help repel the water and shake free .

Polar Bears are the largest land carnivores comparable in size to the Grizzly bear. Male Polar Bears also known as Boars are two to three times larger than female Polar Bears or Sows. Bears weigh 770 to 1400 lbs and are 8-10 feet tall, where Sows weight 330 to 550 lbs and are 6-.5-8 feet tall. A Polar Bears hind limbs are slightly longer than their forelimbs. Polar bears have a thick layer of fat under their skin and thick fur coats that keep them warm in the cold. A polar polar bear weighing Ĺ a ton can punch through solid ice, to hunt a seal.

Polar bears have 42 teeth, that are mainly used for tearing. They swallow most food in large chunks and do not do much chewing.

Polar bears are excellent swimmers. They can swim for several hours at a time and cover a large distance. Polar bears can swim 6 miles per hour. Polar Bears can remain submerged underwater for up to 2 minutes.

Polar Bears are solitary creatures, only appearing in breeding pairs or after a female with cubs.

Polar bears feed on seals, and the carcasses of beluga whales, walruses, narwhals and bowhead whales. If other food is not available polar bears will eat reindeer, rodents, water fowl or vegetation.

Female polar bears reach sexual maturity at 4-5 years, while males mature at 6 years. Competition for females is intense, with females only breeding once every three years. Dominant male polar bears. Gestation of polar bears is about 8 months. Polar Bears give birth in dens and will typically give birth to two cubs at a time. A new polar bear weighs 16-24 oz and are only 12 inches long. Polar bears are born small and helpless with their eyes closed. A cubs fur is very fine at birth, making it appear to be bald.

Polar bear make dens by digging a hole in a snowbank. Unlike other bears polar bears do not hibernate in the winter. From October to December the female Polar Bear digs a den in a drift of snow. The motherís body heat, and milk keep the baby polar bear cubs fed and warm before they leave the den from March to April.

Polar bears are struggling due to melting ice caps and melting sea ice, which is threatening their survival . World Polar Bear populations are estimated to be between 21,000 and 25,000 bears. Polar Bears was added to the Endangered Species Act in 2008.

Polar Bears can live 20 to 30 years, but only a small percentage live past 18 years of age.
