Polar Bears are among the largest land mammals on earth. Males
can weigh between 700 - 1400 pounds and stand between 8 - 10 feet
tall. Females are smaller than males, with weights averaging 350 -
700 pounds. Polar Bears appear to have a white coat; however, the
actual hairs are translucent and clear. The skin of the Polar Bear is
black. The coat and skin are adapted to absorb sunlight and retain
heat. Like many animals of the tundra, Polar Bears have short ears to
minimize heat loss.
Polar Bears will give birth one out of every two to three years. The
mating season occurs in the spring, and the female will then give birth
in the winter to a litter of one to two cubs.
