That’s not a 🦄 you’re looking at, it's a narwhal! #DYK their tusk is part of a set of teeth? One stays embedded in the upper jaw, while the other grows into the spiraled tusk that protrudes out of the upper lip up to more than 8 ft long! #WhaleWeekSI
Happy #FossilFriday! Meet Monodon monoceros, an extant member of the order Cetacea. You might know it by another name... the narwhal! It's sometimes called a sea unicorn because of its enormous tusk—actually an elongated canine tooth that can grow to be nearly 10 ft (3 m) long. pic.twitter.com/645Pb61i3J
