There is the case of the Australian Orcas that used to alert whalers to where the whales were located so they could eat the whale tongues after they had been harpooned.
I have only seen a few Orcas while offshore fishing in Mass Bay. And I have plenty of time out there.
Apparently it doesn't take to many Orcas to wreak havoc on the white sharks, if they are so inclined. - Tom
