Ursus maritimus

Class  

Mammals

Bear (Polar)

Range  

Polar bears are found across northern Canada, Alaska, Greenland and even Russia.

Habitat  

Polar bears live on the freezing polar ice pack.

Body Traits  

They have thick fur. They have more than 4 inches of fat called “blubber.” This protects them from the extreme cold. Males weigh from 700 - 1,500 pounds, while females are only 300 - 600 pounds.

Habits  

They will attack and eat humans.

Diet  

They eat mostly seals, making them the only pure meat eater (carnivore) of all the bears in North America.

Predators  

The only predator that kills polar bears is man, though one polar bear may kill another.

Reproduction  

Females have 2 cubs in their winter den. Polar bear cubs nurse on milk for more than a year and a half. This helps them survive the cold. More than half of all cubs die in their first year.

Lifespan and/or Conservation Status  

If they get past the first year, they can live up to 25 years in the wild. They are listed as a "vulnerable" species.
