The "horn" is an extremely elongated, hollow tooth which always spirals counter-clockwise from the left side of the skull. It can measure 2.5 to 2.7 m long (8-9 ft.). There have been sightings of narwhals with two tusks present. Almost exclusively seen in males, there are only scattered reports of females developing a tusk. Narwhals have no other visible teeth in their jaws.
