Why the confusion? Here are some quick narwhal facts that help explain why people can’t believe these crazy beasts exist: the giant “horn” looks just like the classic idea of what a unicorn’s horn looks like, you can’t find narwhals at any aquariums or zoos, and they live in some of the coldest, most remote places on earth. That’s why people think they’re fake.
So what are narwhal horns made of? The “horn” is actually a tooth, so… tooth stuff. Narwhal tusks are actually inside-out, with the hardest layers on the inside and the softest on the outside. That’s the opposite of how human teeth are formed. As for the unicorn confusion, that stems from Vikings selling narwhal horns as “unicorn horns” to gullible medieval Europeans. Read on for more facts about narwhals that will help clear things up. Spread the word: they’re real!
