Narwhals are unique creatures of the sea, often referred to as the "unicorns of the sea" due to their long, spiral tusk.
They are a species of whale that lives in the Arctic waters around Greenland, Canada, and Russia.
The tusk, which is actually an elongated tooth, can grow as long as 10 feet!
Did you know that a narwal's tusk looks just like a unicorn's horn.
They are in the family of Monodontidae
