It takes a certain amount of courage and confidence to put yourself in a cage and dive into waters shark infested waters. But something like this will throw all that out the window.

The man who filmed the video says this wasn't an attack on the cage and just an accident. "They are temporarily blinded when they open their mouths, so when the shark went for the tuna bait on the rope it accidentally slammed into the cage. They can't swim backwards so it thrust forward through the cage with a diver inside."

Nobody was hurt and the diver emerged unscathed but shook up.
