Arctic and Antarctic

Arctic is the region around the earth's North pole opposite to the Antarctic region in the south pole.
The question is why are the regions named so.

Arctic region is a region where we find Polar Bears. However in Antarctic region we dont come across Bears even though the conditions are more or less similar(The temperature at Antarctic is 2 degrees lesser than the temperature at Arctic). The reason is Arctic region is mostly covered by land so we find polar bears in huge numbers. However Antarctic is also an island and hence no bears are found.

Arctic is derived from the Greek word ARKTOS meaning Bear. The region opposite to Arctic is Anti-Arktos and hence called Antarctic.
