Polar Bears are seen on places like Russia in Summer and in Winter they are seen on permanent ice. They live on the ice in winter because seals spend time on ice and seals are Polar bears main food. Polar Bears make a den in the middle of fall when snow is on the ground. A Polar Bear lives in a den it makes by digging a deep hole in the snow. The Polar Bear gets the cubs inside first then, once inside closes the den. Polar Bears make a den on permanent ice and in between permanent ice and tundra. They make a den because the cubs can get hurt by other animals so the mother makes the den and has cubs inside.
Appearance
A Polar Bear is one of the largest types of Bears in the world and can weigh up to a ton, they grow pretty fast and gain weigh every day. When they are a two month they weigh 25 to 30. As time goes by the cubs grow stronger, bigger and wiser. Their paws grow bigger and can now support them. Their claws let them grip the surface.
A male Polar Bear can be 15 feet and can weigh 1 to 2 tons. A polar bear's fur is actually clear and hollow, with black skin underneath. The hollow fur absorb heat. Polar Bears feet are flat and square shaped so they can grip the ice, and when the bear swims the feet are like ours. Polar Bear's claws help open an animal's stomach and get through the fur and things. The teeth of the bear help bite through its pray. A Polar Bear has very good sense of smell. It can smell about a mile away. Polar Bears can see pretty far away too and their sight is wide not long.
Food
Polar bears hunt alone they are not pack hunters. They are best known for eating seal, blubber meat, etc. They eat the seals blubber and their intestines. The way Polar Bears catch seal is by going to a seals blow hole and when the seal is coming up for air the bear kills it by crushing its skull.
Life Cycle, Mating and Reproduction
Polar Bears start to look for a mate in spring. Polar Bears are like salmon because they move from the place they are born, get pregnant, and then move back to the place they are born and have cubs.
A female Polar Bear usually gives birth to two cubs at a time. When the cubs are born, they are one foot long and weigh a little over a pound. The cubs learn about defense by imitating their mother, smelling what she smells, walking where she walks, and the mother tries to set an example.
In two months after the cubs are born they can walk, and see things for themselves. Polar Bears have a good sense of smell so if a cub were to get out of the den it could find its way back. In another month or so the cubs can leave with their mother because they can walk well and they have their mothers protection. The mother brings the cubs outside every chance she gets so they can learn about their world. They learn how to walk on the ice and snow without slipping and sliding.
