Where do narwhals live?
There are millions of nerve endings in each tusk that may help this species locate food. Over the summer months, the Canadian Arctic is home to about 90 per cent of the world’s narwhal population. They congregate from Northern Hudson Bay to Ellesmere Island to feed and rear their young.
How big are narwhals?
Nicknamed the “unicorn of the sea” and long shrouded in mystery, the narwhal is famous for its long ivory tusk, which spirals counterclockwise and can reach up to nine feet (2.5 meters) in length. Males predominantly have a tusk, and some have two. The tusk — once thought to have magical properties — is actually an enlarged left canine. Narwhals also have a right canine which stays embedded in their mouths. Ongoing research suggests the tusk is used for impressing mates and stunning fish before eating them, and it even has some remarkable sensory capabilities!
