The most unique whale in Nunavut waters is the narwhal, according to Nunavut Tourism. It lives year-round in the Arctic. Narwhal males are distinguished by a long, straight, helical tusk — a modified incisor tooth — extending up to 10 feet in length. Summertime is better for viewing because they move closer to shore. And the best places are the Nunavut communities of Arctic Bay, Pond Inlet and Resolute.
