Swimming effortlessly through icy waters, a polar bear demonstrates the origin of its scientific name - Ursus maritimus. In the frozen high arctic, a polar bear shakes its thick white coat to dry and sends a watery spray into the air. Powerful battles erupt between 700-pound males. In Hudson Bay, an adult bear stands as much as ten feet high to nose its way into a tundra buggy. Flip Nicklin takes us to the icy realm of the polar bear to better illustrate the nature of this creature and chronicle its interactions with tourists and researchers.
