 The NarwhalFound in the Arctic and North Atlantic Oceans, the narwhal is small whale known for the single, tightly spiraled tusk—up to 9 ft (2.7 m) long—that protrudes from the upper jaw of males as well as some females of the species. The tusk is an overgrown, nerve-rich incisor tooth and may be used as a sense organ or to attract mates. Now hunted by native peoples for its meat, the narwhal was formerly killed for its tusk, which was believed to have magical properties and was sold for centuries as what? More...

Strange that the name should reference the skin colour when the most obvious identifier is the bloody great horn (tooth). Quote:náhvalur
Faroese

Etymology
From Old Norse náhvalr, probably from nár (“corpse”) + hvalr (“whale”). Quote:
*nawiz m
corpse

Although when you are looking from a distance, it actually makes more sense. Spot the narwhal....  This narwhal has been with this pod of beluga whales for at least three years, so they are obviously pretty chill.  Quote:
Whale researchers in Quebec’s St Lawrence River are celebrating a remarkable discovery: a juvenile narwhal far from its arctic home, that appears to have been adopted by a band of beluga whales.
The narwhal, more than 1,000km outside its typical range, was filmed by a drone swimming and playing with dozens of belugas that were treating it as one of their own.
With its long, spiral tusk and spotted grey skin, the narwhal stands out from the pack of white St Lawrence River belugas. But its cousins don’t seem to mind, rubbing up against the narwhal and playing sexual games common among young male whales.
Although both are highly social animals, narwhals and belugas don’t typically interact when they meet in more northern waters.
Belugas generally live in more northern waters, but a fluke of evolution means a branch of the species remained in the St Lawrence River after the last ice age. While they’re closely related to narwhals, they do have different hunting and ranging habits.
Drones have given biologists greater access to the secret lives of whales, said Robert Michaud, the president of the Group for Research and Education on Marine Mammals, the organization that made the discovery.
“We see just a fraction of their lives,” Michaud said. “We now have more powerful tools to examine these animals, and actually see their interactions. The more we study these animals, the more we find them fascinating.”
The most intriguing question for researchers is what will happen to the young narwhal as it grows into an adult. Cross-breeding between the two species is believed to have occurred in some limited instances, but it’s rarely been documented.
“If this young narwhal spends his life with belugas, we’ll have a lot of information to learn and share,” Michaud said. “I hope I’ll be there to see it.”
