What is the purpose of a narwhals tusk

[From: ] [author: ] [Date: 11-09-04] [Hit: ]
Visual sexual characteristics are common in the animal world and provide a means for a receptive female to judge the credentials of a competing male (among other things). The narwhal link above leads to a related article should you be interested.......
From wikipedia...
"The most broadly accepted theory for the role of the tusk is as a secondary sexual characteristic, similar to the mane of a lion or the tail feathers of a peacock...It may help determine social rank, maintain dominance hierarchies, or help young males develop skills necessary for performance in adult sexual roles. Narwhals have rarely been observed using their tusk for fighting, other aggressive behavior or for breaking sea ice in their Arctic habitat."
