Why are polar bears white?
The colour varies from pure white to more of a yellow hue. The white fur is important camouflage for the bears as they hunt their prey out on the ice pack. Polar bears are clever in their use of cover, be it land, water, or ice. This aids both their hunting of seals and their own escape from human hunters. The soles of the bears’ feet have small bumps (called papillae) and cavities that act like suction cups which help to keep them from slipping on the ice.
