The narwhal is essentially the unicorn of the ocean, but is, in fact, a real-life animal! Yes, you read that right, they aren’t mythical creatures all. They are whales known for the long spiraling horn coming straight out of the front of their head. The horn is actually an elongated upper left canine tooth, and although rare, it is possible for narwhals to develop two tusks! Narwhals eat many different kinds of fish and can weigh up to about 3500 pounds. This little temporary tattoo is 7 inches long.
