Actually, this shark was rather small, about 9 feet. A great white shark can grow to be over 20 feet. Most likely, it was eaten either by a killer whale, as some suggested, or a much larger shark.
That doesn’t make sense for the depths that thing was recorded at.
Not a killer whale. They're thought to dive to at most to about 30 meters (no need to go deeper, no food down there), whereas the critter that ate this dove WAY deeper, to 590 meters. From what I can glean online, Great Whites can handle the pressure of that depth. A killer whale probably couldn't. That's awful damned deep.
