The Predator That Makes Great White Sharks Flee

Off the southern tip of South Africa, there is a bay where the great white sharks always gathered. For decades it was one of the surest places on earth to find them. And then, almost overnight, they were gone. The first sign was a body on the beach, a great white nearly sixteen feet long, with a single clean wound between the fins and the liver removed. Then a second. Then a third. Something had come into the home of the most feared predator in the ocean and begun taking it apart, one organ at a time. We tell ourselves the great white sits at the top of everything, the last predator, the one with nothing above it. We are wrong. It has a predator of its own, and that predator is the orca. This is the story of the ocean's true apex predator. The killers off South Africa even have names. Researchers call them Port and Starboard, after their collapsed dorsal fins, and when these two appear the great whites do not just die, they clear out, sometimes for months. But the orca is far more than a shark killer. It has no predator anywhere in its range, and its range is very nearly the whole planet, every ocean from the pack ice of the poles to the warm shallows of the tropics. It is not a whale at all. It is the largest dolphin in the world, grown to thirty feet and hunting in disciplined packs. Its menu runs past a hundred and forty species, from fish and seals to the calves of larger whales, and even moose swimming between islands off Alaska. In twenty nineteen, off Western Australia, a pod brought down a blue whale, the largest animal that has ever lived. The orca does not pick on the small and the slow. It goes after the largest creatures on earth, and not out of need, but out of capability. Its sharpest weapon is not its body. It is what it knows. Off Antarctica, orcas line up and drive at a floating ice floe together, sending a single wave that washes a seal into the water. Along the beaches of Argentina, they hurl themselves clean onto the sand to snatch sea lion pups, then heave their bodies back into the surf. None of it is instinct. It is learned, invented by one generation and handed to the next, and it changes from one corner of the world to another the way customs change between countries. Whole families even speak in their own dialects, as particular as a regional accent. In the narrow water between Spain and North Africa, a fragile population has lately taken to sliding up behind sailboats and snapping the rudders, more than seven hundred encounters since twenty twenty. The internet called it an uprising. The scientists who study it think it is something stranger: a game. And then there is the fact that throws everyone. A predator that clears a coastline of great whites just by arriving, that kills the largest animals on the planet, that has us hopelessly outmatched in open water, has never, in all of recorded history, killed a human being in the wild. The only orcas that have ever taken a human life did it inside the concrete tanks we built for them. Out in the ocean, with every opportunity and every reason, they leave us be. We have barely begun to understand this animal. And the ocean, as ever, is in no hurry to explain. Welcome to Blues Below, where we explore the ocean's deepest mysteries one story at a time.
