It's #NarwhalDay! Narwhals were once thought to be the "missing link" to the mythical unicorn. Research has now shown us that the long "tusk" of this Arctic whale is in fact a tooth that protrudes from inside their mouth out through their upper lip. What exactly this tooth is used for is still a subject of study but narwhals have been seen using their teeth to break up small amounts of ice and will sometime "fence" with each other, perhaps in competition for a mate.⠀⠀ Photo by Bryan and Cherry Alexander⠀ #whaletales #whales #narwhal #narwhalsareawesome #whalesofinstagram #whalewatching #storytelling #whalesareawesome #narwhalsofinstagram⠀ https://www.instagram.com/p/BwFTY5Ngy32/?utm_source=ig_tumblr_share&igshid=xruk2tv46tb4
