"What might appear to be an aggressive great white shark trying to attack the cage, this is not the case. These awesome sharks are biting at large chunks of tuna tied to a rope," the man who posted the video, who did not want to be named, wrote on YouTube. "The diver is a very experienced dive instructor, remained calm, and when the shark thrashed back outside the cage, the diver calmly swam back up and climbed out completely uninjured."

Footage shows the shark repeatedly flipping and turning. At one point, its body lay on top of the cage on the surface of the water.

"It happened so fast. The other divers just kept telling me how lucky I am," Chan told ABC News.

Chan, who survived unscathed, plans to go back into the water.
