Weighing 1,400 pounds, polar bears are lords of the ice--creatures perfectly adapted to the harshest and most unforgiving climate in the world. Biologist and photographer Dr. Dan Guravich has dedicated himself to capturing this creature's magnificence on film. The Canadian-born photographer, who makes his home in Mississipi, has made over 50 trips to the Arctic to practice his art. Through his dramatic photos, Guravich has profoundly influenced our understanding of these mysterious animals.
