Monodon – Narwal

Their large ivory tusk which is a protruding canine tooth of the male makes them The ‘unicorns of the sea’  

Narwhal has a mottled pattern, with blackish-brown spots on a white background, but older males can be almost entirely white. However, a newborn is blotchy gray and becomes whiter with age. The long tusk or canine tooth projects from the left side of the upper jaw, then through the lip, and forms a helix spiral.

There have been speculations about the function of the tusk including acting as a weapon, as an acoustic organ, as a secondary sex character, and for opening breathing holes in the ice. Their diet consists of shrimp, squid, and fishes such as Arctic cod. They are hunted for their meat, skin, and tusks that can be used for carvings.
