The polar bear is the world’’s largest bear. Females can weigh over 650 lbs, while males can weigh more than double that weight.
Polar bears are great swimmers, they have been seen in open waters hundreds of miles from the land.
Males are active year round, while females usually hibernate in ice
dens during the winter. A female polar bear will give birth to their
young inside of these ice dens, and then emerge in the spring.
