Apparently, when a pod of wild beluga whales ran into a lost male narwhal—a kind of toothed whale—in the St. Lawrence River in Quebec, Canada, they befriended him and took him in as one of their own.
In drone footage taken by the Group for Education and Research on Marine Mammals (GREMM) in July 2018, the lone dark-gray narwhal is seen swimming alongside a group of around 10–11 juvenile pure-white beluga whales—believed to be mostly males, CBC News reported.
