The narwhal is a marine mammal from the order of cetaceans. Males grow a long spiral tusk that emerges from the upper jaw and resembles a horn.
The narwhal differs from other whales with a long tusk only in males. It is important for Arctic nature as a fish hunter and an indicator of the health of polar seas.
