The “horn” of the narwhal is actually the left canine of the whale. It endures severe pain and allows it to pierce the upper lip, protruding straight upward from the left upper jaw. The average length of this “bucket” is 2 meters, and the longest can reach 3 meters.
In addition to fighting, teeth are also a symbol of their status in the family. The longer and thicker the narwhal’s teeth, the higher its status in the whale group.
