Photos: Reindeer, the animal that helps pull Santa's sleigh
New Delhi/ 26 December 2016. Reindeerâwhich are called caribou in North Americaâplay an important role in Christmas folklore. But the deer is more than mere myth.
In the Arctic, indigenous peoples such as the Nenets rely on reindeer for food, transportation, and clothing year-round. Wild reindeerâwhich live in Scandinavia, Siberia, Greenland, Alaska, and Canadaâalso benefit their ecosystems. For instance, they serve as prey for polar bears and wolves.
Here are some glimpses.
