The Mysterious and Dangerous Behavior of Killer Whales Towards Boats

An orca repeatedly rammed into a yacht in the North Sea near Scotland's Shetland Islands, exhibiting behavior that has been seen in killer whales farther south. The incident bore a striking similarity to dozens of incidents reported this year in waters near Portugal and Spain. The behavior's origin is still unclear, with some scientists believing it's a playful or social behavior, while others think it's a defensive response to boats. The incidents have inspired jokes and memes about an orca uprising, but experts don't believe it's an actual cetacean revolution.
