Legend ¬†of the Unicorn
One legend stems from the vertebrate (The Narwhal) whose tusk is alluded to as alicon.
The Norwhal ( unicorn ) is one of the rarest whales realized that lives in the Arctic. The male of this species has a solitary left tusk that is an adjusted upper incisor. The tusk is spirally curved, typically in a counter clockwise position. In a full grown example the tusk could be 2 to 7 metres in length. One horn in Liverpool University is accepted to have been from the horn of a Narwhal, measuring 110cm long with a width of 5.2cm, decreasing to 2.5cm. The Narwhal is not an imperiled species, not, one or the other is it chased industrially.
