The Arctic Ocean is so cold that it takes special plants and animals to survive there. White polar bears stroll along sheets of pack ice. Whales swim and sing under the surface of the water. Deep below, on the ocean's bottom, live mysterious creatures like sea spiders and snow crabs. Above, miles and miles of snow and ice create a world of white and glaciers soar into the sky like frozen mountains. Put on your winter gear, and have an adventure exploring the ocean at the North Pole.
