The area around the North Pole is called Arctic. The area around the South Pole is called Antarctic. Both are cold and ice-covered regions. But there is sea water under the ice sheet in the Arctic region while it is rocky mainland below the ice caps in the Antarctic region. It is why Antarctic is called a continent. The Antarctic region has Penguins. But they are not found in Arctic region. Many sea birds such as the albatross also breed in the Antarctic. In the Arctic, which lies above Canada, Siberian region of Russia, Alaska and Scandinavian countries, polar bears and a species of seal with huge tusks, called the walrus, are found. Huge whales swim off the coasts of both the regions.
