Super narwhal5/13/2023 Sometimes these groups become trapped by shifting pack ice and fall victim to Inuit hunters, polar bears, or walruses. They are often sighted swimming in groups of 15 to 20, but gatherings of hundreds-or even several thousands-of narwhals have been reported. Like some other porpoises, they travel in groups and feed on fish, shrimp, squid, and other aquatic fare. Narwhals are related to bottlenose dolphins, belugas, harbor porpoises, and orcas. Females sometimes grow a small tusk of their own, but it does not become as prominent as the male's. Scientists are not certain of the tusk's purpose, but some believe it is prominent in mating rituals, perhaps used to impress females or to battle rival suitors. The ivory tusk tooth grows right through the narwhal's upper lip. In males, the more prominent tooth grows into a swordlike, spiral tusk up to 10 feet long. The narwhal is the unicorn of the sea, a pale-colored porpoise found in Arctic coastal waters and rivers. Current Population Trend: Unknown What is the narwhal?
