Polar Bears :: essays research papers

Habitat Polar braves prefer to live in extremely cold artic climates. They live only in the Federal Hemisphere, on the galosh ice cap, and they spend most of their time on coastal areas. Polar take ins are widely spread in Canada, extending from the northern arctic islands south to the Hudson Bay area. They are to a fault found in Greenland, on islands off the shore of Norway, on the northern coast of the former Soviet Union, and on the northern and northwestern coasts of Alaska in the United States. Physical FeaturesThe polar bear is one the largest members of the bear family. Males Polar Bears stand from eight to 11 feet tall and by and large weigh from 500 to 1,000 pounds, but can weigh as much as 1, cd pounds. Female bears generally stand eight feet tall and weigh 400 to 600 pounds, except some, which can reach 700 pounds. The reason the polar bear weighs so much is that is stores about a four-inch layer of fat to keep it warm.The polar bear has a long, narrower head and no se, and small ears. The polar bear has coat that appears white but, each individual hair is actually a clear and hollow. This helps the polar bear keep warm. The polar bears coat helps it blend in with its snowy surroundings, this adaptation helps the Polar Bear hide while hunting. The polar bears front legs are sparingly pigeon-toed, and fur covers the bottoms of its paws. These adaptations help the polar bear keep them from slipping on ice. DietThe polar bear rarely eats plants. That is why it is considered a carnivore, or perfume-eater. The ringed seal is the polar bears primary prey. A polar bear hunts a seal by waiting quietly for it to emerge from an opening a seal makes in the ice allowing them to breathe or climb out of the water to rest. Polar bears eat only the seals skin and blubber of the seal. The remaining meat provides a food source for other animals in the Arctic. Polar bears also prey on young walruss. The remains of whale, seal, and walrus are also important sour ces of food for polar bears. In fact, because of their acute sense of smell, polar bears can sense animal remains from far away. BreedingBreeding normally takes place in April to June. Polar bears reach breeding maturity at three to five years of age.
