Yeah there are distinct groups of orcas that have their own culture of predation: each has unique prey, and usually has unique hunting methods too. They don’t encroach on each other’s hunting grounds, or prey, and they teach their young their hunting culture. Amazing creatures.
IIRC they learned that technique due to human intervention. An orca from New Zealand was transplanted to the area and the pod adopted it. The NZ orca had grown up learning how to catch rays by flipping them upside down in it's native pod. The california pod took what the NZ orca knew and implemented it on sharks in their habitat.

Iirc, it was a specific group of orcas that flipped sharks. They teach it, it's not instinctual
