Learn all about the Narwhal. This medium-sized whale has a tooth growing right through its lip.

An Illustration Of A Narwhal.
The Narwhal is a medium-sized toothed whale that belongs to the Monodontidae family. The only other member of this family is the Beluga whale.
Narwhals are easily distinguishable by one unique feature: males of the species, and even a few females, have a large “tusk” that protrudes out of their mouth. In fact, this tusk is an “overgrown” canine tooth that pierces through the left side of their lip.
This spiral-shaped tusk was once touted in past centuries as a unicorn’s horn and sold as such to unsuspecting buyers!
