Content: The tusk can even detect barometric pressure when it is above the water’s surface. The heart rate of narwhal changes when the tusk is exposed to different levels of salt in the surrounding water. They can taste chemical concentrations in the water. This helps them to find food, but also females that are ready to mate. Humpback whales are huge but they do have predators. Find out what attacks them here
Echolocation
Researchers have discovered that narwhals use echolocation. They have the most directional sonar ever detected. They can navigate through dark and murky waters by producing clicking sounds. These sounds are made up to the rate of up to 1000 clicks per second. They can reconstruct their surroundings using the echoes as the sound waves bounce off nearby rock formations or prey.
