Easily recognized by its long, spiral tusk, the narwhal (Monodon monoceros) is also known as the Unicorn of the Sea. A narwhal is a whale that has mottled grey skin with a single spiral “tusk” protruding from its upper jaw. The tusk has been highly valued since the Middle Ages, when they were thought to be magical unicorn horns.

Since tusks are worth so much money, there has been an increase in hunting these whales. The International Union for the Conservation of Nature has therefore classified narwhals as a Near Threatened species.

Many people save narwhals by setting up special laws against hunting. For example, there is a limit on the number of narwhals that can be hunted and every tusk obtained must be labeled. It is important to save narwhals because they play an important role in the overall health of the marine environment.
