Antarctica is one of the seven continents of the Earth, located below the Antarctic Circle. 98% of the continent is covered with ice, and it has no native human population (due in large part to the freezing temperatures and high winds). Scientific researchers staff various research stations on a rotational basis, but the largest demographic group, in fact and popular fiction, consist of penguins. Various breeds of seals and whales and other marine animals are also native fauna.
