For the Eskimo who lives in the lands around the Arctic Sea, the seal is a very important animal. From the seal he can get money of the things he needs to live. He saves the skin to furnish material for his boots and clothes, and even to make the cover for a small boat.

Its lungs hold enough air to allow it to stay under the water for several minutes. Read more....
