Huge, powerful and fearless is Nanook, the polar bear. Standing 10 feet tall on its hind legs, reaching more than 1,600 pounds and renowned for its singular ferociousness, the polar bear reigns in the North. It survives on the starkly beautiful arctic tundra, which provides a natural camouflage. And with its tapered profile, tufted ears, snowy white coat, and coal-black eyes and nose, the polar bear is arrestingly photogenic. In this remarkable collection of photographs we discover an animal that is not only a fierce predator, but also a loving parent and a natural jester. Internationally renowned nature photographer Norbert Rosing has been a leader in raising awareness of this majestic but often misunderstood -- and increasingly threatened -- creature. In Polar Bears 2006, his engaging photographs and informative captions invite us into a world that few ever see.
