Narwhal, the Unicorn of the Sea



The legendary narwhal is famous for its unicorn-like single tusk. The narwhal, or narwhale (Monodon monoceros) is the unicorn of the sea.

These 3,500 lbs (1,600 kg) creatures have two teeth and in the males, the more prominent tooth grows out through the upper lips into a long swordlike, spiralled tusk that can reach 2.5 metres (8.8 feet) in length.

It is believed by some scientist that the tusk is prominent in mating rituals, perhaps used to impress females or to battle rival suitors.

Females occasionally grow a small tusk and males have been seen with two, or none.

Narwhals are inhabitants of Arctic coastal waters and rivers. They are related to bottlenose dolphins, belugas, harbor porpoises, and orcas.
