Drone footage uncovers the function of the famous Narwhal tusk
Scientists with the World Wildlife Fund studying Narwhals in the Canadian Arctic may have just uncovered the mystery surrounding the function of the narwhal tusk. Narwhals are famous for the ivory tusk that juts out from its mouth, up to nine feet long, but the function was never proven until now. Researchers using a drone to film Narwhals recorded never before seen behavior of the whales stunning fish by smacking them with the tusk in order to more easily eat them. Image from Shutterstock.
