Content: Sensory Organ
The tusk of a narwhal is covered in thousands of nerve endings and pores. This helps the narwhal sense and feel the environment around them. With their tusk, they can feel their surroundings. The tusk acts like having a giant antenna-like sensor. They can detect water pressure, temperature, and salinity. 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.
