An Indian rhinoceros is also known as the "great one-horned" rhinoceros. This being said, the rhinos are known for having one large horn that begins to show after six years of age in both men and females.
A Narwal has one tusk. It comes out from its upper jaw, and is actually an extension of its upper left hand tooth. The tusk only occurs on a male, and is normally spiralled in an anti-clockwise direction. The tusk is hollow. The purpose of the narwhal's tusk is not actually known, but it is theorised that its used in courtship, as a weapon in competition with other males, and even to enhance its sonar functions.

A male narwhal tends to have just one tusk. The tusk grows out from the incisor tooth on the upper left jaw. But there are rare instances of a narwhal having two tusks. The second tusk tends to be a smaller version of the main one. It grows out of the right incisor.
A narwhal (Monodon monoceros).
Narwhal
Answer #1 by Mediatech Narwhal are mammals, so they do not lay eggs. Answer #2 by Ginezumi Hunters want narwhal body parts if they seek food, and narwhal tusks if they seek profit. The narwhal has a long, curved tusk that projects frontwards out through the mouth. Inuit hunters generally are interested in narwhal body parts as sources of food. Non-Inuit hunters generally aren't interested in narwhal body parts as food. They seek the narwhal's tusk.
Many mammals have tusks, including elephants, boars, and of course, narwhals.
A walrus has ivory tusks. A narwhal has a single ivory tusk.
The longest Narwhal tusks can run over ten feet. They range in size from 4 ft 11 in to 10 ft 2 in.
Most narwhals have just the one 'tusk', and it is actually a tooth. One in 500 males have two tusks, but the skull has a double tusk'.
Because Inuit hunters kill them for there skin and tusks. Hope this helped
Firstly you don't need to say whale after narwhal, secondly the unusual fact about them is that their horns are infact tusks and are very suseptable to pain.
A narwhal is a tooth whale, but has a special feature separating it from any other whale, which is a twisted tusk growing out of the left part of its mouth. Scientists have examined narwhal tusks a lot, and have found that there are special blood vessels in the tusk. They think that they use their tusks to communicate, but there is only a slight chance that they are right. Thus, they haven't found out much about the narwhal's tusk yet.
A tusk really is a tooth. Therefore, there are elephant, narwhal and walrus tusks. Tusks sometimes are called horns. But horns aren't necessarily teeth. An example is the rhinoceros, whose horn isn't a tooth at all.
