Kings Of The Arctic

"The Polar Bear is like the lion of the north. It is the king." - Gabriel N.

Polar bears blend into the snow and ice. They weight more than half a ton. They live in the Arctic because of their thick fur. Polar Bears have a very long body shape. They have long necks to keep their head out of the water. Polar Bears are classified as Marine animals because they relay on the ocean to provide food.

Land of Polar Bears

"For humans the Arctic is a harshly inhospitable place, but the conditions there are precisely what Polar Bears require to survive and thrive." -Sylvia Earle.

Standing male is 8 feet tall, he can weigh greater than or equal to 1700 pounds. Females weigh an average of 330 to 880 pounds. There are about 20,000 to 25,000 Polar Bears in the Arctic. There are 4 different ice regions in the Arctic. The oldest Polar bear recorded was 32 years old.

Life Begins On The Ice

"Polar Bears are creatures of the sea ice. If it disappears so will they." - Kieran Mylvaney. New born Polar Bears weigh about a pound. When they are born they have no hair and are small and pink. Polar bears don't hibernate. Their dens are forty degrees warmer than outside. A Polar Bear has swam for nine days. In the summer Polar Bears have to jump into the ocean so they won't over heat.

Polar Bear's Food Sources

Polar Bears eat hooded harp. They also eat seal. They have to eat about one 150 pound seal per week to survive. They can eat carcasses of walruses and beluga whales. They feed on caribou, birds, eggs, and berries in the tundra. In the water they eat plants like kelp. They can travel 20 miles in one day to find food.

Polar Bear Cubs

Before they have cubs, females have to store energy. In the winter the mother digs a den six to nine feet long and wide. They normally have two cubs. In the spring they weight twenty to thirty pounds. Cubs spend more time outside having not eaten for months. Adult male Polar Bears don't have predators but cubs and females do.
