The parallel line of latitude that circumscribes the polar tundra zone is the Arctic Circle in the Northern Hemisphere and the Antarctic Circle in the Southern Hemisphere. These circles mark the approximate southern and northern boundaries of the tundra biome where the cold climate and limited vegetation characteristic of tundra regions are found.

The polar ice caps are surrounded by the polar tundra biome. This biome is characterized by cold temperatures, permafrost, and a short growing season with low-lying vegetation. Many arctic animals, such as polar bears and arctic foxes, are adapted to survive in this harsh environment.
