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.
Narwhals feed in deep bays and inlets, where they find a good supply of Arctic cod, squid, flatfish, and shrimp.
While usually seen in groups of 20-30 animals, sometimes narwhals form groups of up to 1,000 during their migration within the Arctic Ocean.
The narwhal, beluga, and the bowhead are the only whales that spend their entire lives in the Arctic.
