Here's why:
* Habitat: Reindeer are adapted to cold, snowy environments and thrive in the tundra and boreal forests found in the Arctic regions of the world.
* Food: They rely heavily on lichens, mosses, and grasses that grow in these environments.
* Antarctic: The Antarctic Circle has no landmass that supports the kind of vegetation reindeer need to survive.
While there are some species of deer in the Southern Hemisphere, none are found in the Antarctic region.
