The male narwhal's straight single helical tusk, which usually grows out from the left of the mouth, is an exception to the typical features of tusks described above.

The tusks are used to push through the dense undergrowth of their habitat. [14] The largest tusk recorded for the species is 2.41 metres (7.9 ft) long and 60 kilograms (130 lb) in weight. A larger tusk measuring 2.96 metres (9.7 ft) long and weighing 70 kilograms (150 lb) has been recorded, but this may belong to a forest-bush elephant hybrid.
