This tusk is from a small toothed Arctic whale called a narwhal. Only the male of the species develops this twisted growth, which originally forms from a tooth. For centuries such tusks, which could grow several metres in length, were claimed to be from the mythical creature the unicorn.
The narwhal was scientifically described by Carl Linnaeus in his 1758 publication Systema Naturae. [5] The word "narwhal" comes from the Old Norse nárhval, meaning 'corpse-whale', which possibly refers to the animal's grey, mottled skin and its habit of remaining motionless when at the water's surface, a behaviour known as "logging" that usually happens in the summer.
Tusks are generally curved and have a smooth, continuous surface. 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. Continuous growth of tusks is enabled by formative tissues in the apical openings of the roots of the teeth. [2] [3]

A former Royal Canadian Mounted policeman accused of smuggling $2 million worth of narwhal tusks into the United States is now in custody.
In particular, the characteristic narwhal 'horn' is anatomically a tooth; the unidentified specimen lacked a single narwhal tusk, but its teeth were spiraled, like the tusk of a narwhal. [ 5 ] [ 3 ] The specimen had 18 teeth, an intermediate number when compared to the beluga (40 teeth) and the narwhal (one tooth).
The tusk Templeton found is so large because it came from a Columbian mammoth, an animal that could grow up to 15 feet tall at the shoulder and weigh in excess of 10 tons.
