Do female narwhals have tusks

A female narwhal does not typically have a tusk, but yet not all males do, either. About 15% of female Narwhals have these tusks. The truth is, scientists don't yet know why most males have them, and most females don't. They do, however, know that the so-called "tusk" is really a tooth that has grown through the upper lip. Narwhals only have two teeth. Sometimes both of them will grow through the upper lip, and other times, neither tooth will grow out like this. Scientists are still trying to figure out why that is, and it may take a while, but eventually they will have an answer.
