Shark watchers were baiting the 13-foot great white shark when it came up against the supposed shark-proof cage and just swam right inside.
“What might appear to be an aggressive great white shark trying to attack the cage, this is not the case,” wrote the cameraman on YouTube. “These awesome sharks are biting at large chunks of tuna tied to a rope. When a great white shark lunges and bites something, it is temporarily blinded. They also cannot swim backwards. So this shark lunged at the bait, accidentally hit the side of the cage, was most likely confused and not able to swim backwards, it thrust forward and broke the metal rail of the cage.”
