Sea Creature Fun Facts: Narwhal

The narwhal is a medium-size toothed whale. -- The narwhal only has two teeth, and one of them can grow into a long tusk. Scientists aren’t sure yet what they use it for. -- Not all females grow tusks, but all males do and some of them even get to 9 feet long! Some people think that this spiral tusk is the source of the myth of the unicorn.
