Killer whales perfect a ruthless trick to hunt great white sharks

In the Gulf of California, a pod of orcas known as Moctezuma’s pod has developed a chillingly precise technique for hunting young great white sharks — flipping them upside down to paralyze and extract their nutrient-rich livers. The behavior, filmed and documented by marine biologists, reveals a level of intelligence and social learning that suggests cultural transmission of hunting tactics among orcas.
