How do polar bears find food?

Polar Bears are expert hunters. They usually hunt in areas that interface between ice and water. They rarely hunt in open water. They use a technique called "Still Hunting". They use their excellent sense of smell to locate a seal breathing hole and wait for the seal to appear. When the Seal comes out to breathe, the bear smells its breath, reaches into the hole with its front paws and drags it out of the water. They kill the seal by biting its head. They often raid the birth lairs of female seals and prey on the seal pups. They are extremely powerful and can even kill an adult walrus.
