Eyewitness DVD: Arctic and Antarctic

Here is an exciting and informative guide to the vast, icy wastes at the ends of the earth.

See a seal with a "trunk," a bear in a burrow, icebergs bigger than skyscrapers, 200-year-old snow goggles, and a pony's snowshoe.

Learn about the northern and southern lights, the crushing power of ice, why Amundsen beat Scott to the South Pole, how penguins keep warm, and what reindeer eat.

Discover why layers of clothing retain body heat, which birds are known as "pirates of the air," which mammals live farthest north, how long a walrus feeds on its mother's milk, whether lemmings commit mass suicide or not, and much, much more!

This award-winning series features stunning photography and graphics to bring science to life.
