Content: Narwhals have the edge over all other echolocating species since they can sense the tiniest of stimuli. This is because their tusk has no protection of external enamel and so is very sensitive. The tusk plays an important role in echolocation when seawater enters through the pores in its tip. Bubbles then travel through the shaft, exciting nerve endings at the tooth base near the head. Signals are then sent to the brain about the narwhal’s surroundings. Weapons
Male narwhals do use their horns to intimidate other males. They go side by side, crossing tusks and rubbing them together in a type of combat. This action is known as tusking. In their territorial battles, narwhals use their tusks to hit their enemies. It is very costly to do this, as their appendages are very sensitive.
