Content: Normally, females do not have horns. Horns are mostly a male feature. Occasionally, however, female narwhals grow one. Since only a few females grow horns, it shows us that the tusk is not really meant for survival or feeding since females manage to live longer than males. The tusk has more to do with courtship and mating. Scientists consider the tusk a male sex characteristic. Only 15% of female narwhals grow a tusk. The tusk is smaller than the males and does not become as prominent as a male’s tusk. Many times, the female tusks fall off. Although many females do not grow tusks, looking inside the upper jaw of a female narwhal and removing bone sections, you can find two small tusks that haven’t broken the surface.
