Are narwhals used by humans in any way?

The hunt and the use of the narwhal tends to be regulated. In part, the regulations are intended to protect the narwhal and to benefit the Inuit peoples of northern Canada and western Greenland. Narwhal hunting happens to be a traditional activity around which the entire Inuit culture revolves. In fact, the Inuit use just about everything that's edible/usable from the narwhal: blubber, meat, organs, and skin.
