Footage has emerged of a great white shark breaching the side of a cage while a diver was underwater during a shark feeding experience off the coast of Guadalupe Island.
Posted on YouTube, the video shows stunned onlookers as a 4-metre-long shark approaches the cage at the back of a boat.
YouTube user Gabe and Garrett wrote: "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."
Gabe and Garrett aded: "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."
The diver moved to the bottom of the cage where he remained calm and eventually exited the water completely uninjured.
