Polar captures a land of extremes - remote, mysterious, and sparsely populated by creatures found nowhere else. Penguins waddle in their irresistibly happy way. A walrus lumbers across the snowy landscape. There's a polar bear with her cubs; a beluga whale breaching; a team of sled dogs sprinting directly at the viewer. And the miracle of the northern lights, shimmering likes a silk rainbow. Science writer Carol Kaufmann brings the reader along on a voyage to the icy North and South Poles and writes a lively and informative essay for each image, including the animal's size, range, habitat, and other vital statistics. Polar captures a hauntingly beautiful yet threatened world, caught forever in moments of living motion.
