I suspect this is fake and staged to get the YouTube hits. I imagine the diver was in a different cage as they set it up for the shark to go through the cage on camera. Maybe I’m too distrusting, but there are a lot of liars and fakes out there, and this looks like one of them.
The shark is also bleeding from the gills, so something else happened off camera, too
Fake. Ok.
“I imagine the diver was in a different cage as they set it up for the shark to go through the cage on camera.”
You may be correct. Let’s call BS on it until we see the footage from his camera, showing the shark in there with him.
