## Quick answer

The narwhal is an Arctic whale famous for the long, spiraled tusk that grows from the head of most males. The tusk is actually an enlarged tooth packed with nerves. Narwhals live year-round in the icy waters of the Arctic, reach about 5 m (16 ft) excluding the tusk, and can live 50 years or more.

## The tusk that inspired unicorns

The narwhal's spiraled tusk is its most famous feature — a single tooth that grows straight through the upper lip and can reach 3 m (10 ft) long. Found mainly in males, it is packed with millions of nerve endings, making it a sensitive organ as well as a possible weapon. In medieval Europe, narwhal tusks were sold as unicorn horns for enormous sums.
