All the reindeer have antlers. It's one of the defining characteristics of a reindeer. The antlers are a symbol of strength and agility, and they play an important role in the reindeer's survival. During the winter months, the antlers are covered in fur to protect them from the harsh cold, and they shed their fur in the spring, revealing their bare antlers once again. The antlers are also used to fight off predators, and to compete for mates during mating season.
