Narwhal Coloring Pages are a great way to learn about this interesting sea creature. A Narwhal, the “unicorn of the sea” is a 16′ whale with a large tusk that’s actually a tooth. The tusk on a male can grow almost 10 feet long! Nobody really knows why they grow a tusk this long since they don’t use it for feeding. Could it be used as a sonar system? or are they just showing off? We may never know, but you can color it! Print all of our pages for free.
