Content: Echolocation also helps them find food. Narwhals eat flatfish, shrimp, cod, squid, and crabs. These can be found on the seabed during their long dives. Narwhals have an interesting way of eating. They suck up their food as they create a vacuum in their mouth. 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.
