The Latin name Monodon (monoceras) translates into single tooth, and correctly describes what is actually an elongated and articulating tooth extending generally from the lower left-hand side of the jaw, more normally referred to as a tusk.
For those of your readers fascinated by this little-known animal, there is a recently published book by F. Breummer devoted to the narwhal.
