Content: This is the front tooth that protrudes beyond the upper lip. It grows throughout the narwhal’s life and can be as long as 10 feet. After maturing, it grows and spirals towards the left. Unlike most mammalian teeth, they have a soft outer layer and a tough inner core. Some species can have a rare second tusk (usually one in 500 males). Contrary to males, only 15% of females grow a tusk which is often smaller than that of the male. The tusk is also considered to be a sensory organ that contains millions of nerves. This provides the narwhal with information regarding the environment it is in. Narwhals are known to rub their tusks with each other as means of communication. Narwhals can also use the tusk to stun any fish by tapping them so that feeding is made easier.
