Reindeer differ from other types of deer in that both male and female reindeer grow antlers, although female antlers are smaller and simpler than those of the males. The antlers themselves are long, with moderate branching on both the main beams and forwardly pointing brow tines. Reindeer use their antlers and feet to protect themselves and to fight for mates during rutting season in the fall. While the antlers are growing, they are covered by a layer of skin and fuzzy fur. In the fall, during rutting season, the velvet is shed, leaving smooth, hard antlers.
Reindeer often rub against trees and underbrush to help speed up the shedding process.
Every spring, reindeer antlers drop off to allow for growth of new antlers. These antlers are often harvested and used to make artwork and other products. Reindeer play an important role in allowing people to survive the harsh environment of arctic regions in the world. They are domesticated in some polar regions, and provide transportation for the people who live there. They are used as pack animals, to carry heavy items, and as draft animals to pull sleighs and carts.
