The Polar regions are the areas around the North Pole and the South Pole.
The Antarctic is a continent surrounded by ocean and the Arctic is an ocean surrounded by continents. Antarctica, or the south pole region, is a continent which is covered with an immense ice shelf. No terrestrial mammals live in Antarctica, but marine mammals include whales, porpoises and seals. There are terrestrial mammals in the Arctic which include musk ox, reindeer, caribou, fox, hare, wolf, lemming, bears, and more. Marine mammals include whales, porpoises, seals, and amphibious mammals. In Antarctica, there is no record of primitive humans and no native groups, but here are native people with a long cultural record and ethnic groups on continents all around the Arctic.
Though the Arctic is obviously a very cold region, it is still much warmer than Antarctica in the South. Known as “the land of the midnight sun,” the Arctic is located in a landmass above 12 frozen feet of ice. The average temperature in Antarctica is -55°C, and the continent covers the entire area from the South Pole to the southern polar circle.
Polar bears live solely in the Arctic areas, while penguins on the other hand, are found in the southern Antarctic regions. For that reason polar bears and penguins never cross paths.
