Canadian researchers said they have identified a mysterious new type of killer whale that hunts large mammals, such as gray calves, and prefers deep-water Pacific canyons for hunting than along the coast, according to reports.
Josh McInnes, a researcher at the University of British Columbia, said these “transient outer coast whales” are a subset of transient orcas known as Bigg’s Killer Whales, according to the CBC. But he said these whales have a distinct vocal dialect from their cousins and spend most of their time cruising the continental shelf off California. Their calls tend to be higher pitched.
Hakai Magazine reported that scientists have long assumed that killer whales found from “Southeast Alaska to Southern California belonged to a single West Coast population.”
The report says the researchers observed 100,000 images and identified 150 members of the new group. McInnes said they would be “great whale hunters” and ambush gray whale calves.

“It’s very, very complex and exciting, and we’re just starting to scratch the surface,” he said, according to Canada’s National Observer.
