Narwhal Tooth

Some whales are baleen whales and others are toothed whales. And then you have the narwhal, which falls in the latter group but really is famous for just one of those teeth. The spiraled narwhal tusk, clearly stolen from a unicorn, is a 10-foot tooth the animal uses to hunt. The narwhal’s body is a little under 20 feet, so in human terms, it’s like a 6-foot man having a 2-foot canine. It’s more evidence—as if we needed any—that nature is the best inventor there is.
