Nope. NOT Orcas (Killer Whales). They don't dive 2,000 feet, they typically only stay down for about 15 minutes at the most (average dive lasts much less, as in a few minutes to about 10 minutes) before surfacing to breathe, and when they take BIG critters, they have to stun them to kill them, then break them down to eat them, swallowing portions whole. When observed eating Great Whites, they eat them at the surface, and also hunt them in groups.

Therefore, whatever took this Great White was most likely a fish or a cephalopod, NOT an aquatic mammal -- an Orca is a mammal just like thee and me!

Orcas play around with sharks and other animals, it could be they didn’t kill it to eat it. I think one of the things they do is bite off all the fins in a playful manner.

There’s video of them doing it to a tiger shark, but that was near the surface like you say. But of course one would think that surface video would almost invariably be the one humans get to see, of course that doesn’t mean they actually do hunt sharks deep. If the transmitter was on the dorsal that could explain how it got in an orca belly I suppose.

Okay, maybe not an orca, but a sperm whale could take on a white shark, and they dive to that depth several times a day.
