The horn is spirally twisted and can grow up to 10 feet long, making it one of the longest teeth in the animal kingdom. The narwhal horn is also remarkably sensitive, containing millions of nerve endings that allow the narwhal to detect changes in its surroundings.

Others think that it may be used for attracting mates or intimidating rivals. The horn may also be used for breaking ice or defending against predators. Despite its many possible functions, the narwhal horn remains an enigmatic and fascinating aspect of the narwhal whale.

However, the trade in narwhal horns is heavily regulated, and the hunting of narwhals is strictly controlled to protect these magnificent creatures.
In conclusion, the narwhal horn is a fascinating and enigmatic aspect of the narwhal whale.
