The Arctic has a wider variety of animal life than Antarctica. The North Pole is in the middle of the Arctic Ocean which is surrounded by the land masses of North America, Europe and Asia so there is a land connection meaning that land animals can more easily reach the Arctic unlike Antarctica where animals must be able to swim or fly there across hundreds of miles of frigid and storm-prone ocean even at the narrowest point.

The animals of the north polar region can be seasonal visitors at the edge, permanent residents of the High Arctic or anywhere in-between.
