Narwhal
Narwhals live in the icy waters of the Arctic seas. The Narwhal's thick skin, called blubber, keep them warm in the cold water. They do not go far away from ice. Narwhals live in groups of between 10 and 100. Narwhals are migrating animals who like to move from one place to live in another place for a while. In summer, groups of them move closer to land, where they can sometimes be seen in the estuaries, deep fjords, and bays of Greenland, Northern Canada and as far eastern Russia. In Winter they move back to the icy waters, where they breathe from small holes in the ice.
