Narwhale (Monodon Monoceros)
Narwhals are native to the cold waters of Canada, Greenland, Norway, and Russia. They can live up to five months under the frozen water. Narwhals have a long spiralled tusk that rows from their forehead. This “tusk” is actually an enlarged tooth that can grow up to 10 feet. This tusk has up to 10 million nerve endings in it, along with being a way that males assert their dominance. Their main food source is Greenland Halibut but they also feed on shrimp and squid. There are more than 80,000 narwhals in the world today.
