Facts about Narwhal Tusk Functionality
- 05
Tusk length in narwhals can reach up to around 3 meters, making it one of the longest teeth relative to body size among living mammals.
- 04
Research suggests narwhal tusks function as sensory organs, detecting changes in water pressure, temperature, and particle gradients to help narwhals navigate Arctic environments.
- 03
A narwhal's tusk grows almost exclusively on the left side, with right-sided tusks being rare, and some narwhals develop two tusks simultaneously.
- 02
Male narwhals occasionally cross tusks in a behavior called 'tusking,' which researchers believe may help detect differences in ocean salinity or temperature.

The narwhal's elongated tusk is actually a modified canine tooth that grows through the upper lip and contains millions of nerve endings sensitive to environmental stimuli.
