hypnotising the predator. The footage, which was filmed in Jupiter, Florida, shows experienced diver Michael Dornellas, 32, coming to the aid of the shark. Using a technique called tonic immobility, he puts the 10ft shark under a type of hypnosis - allowing him to remove the hook from its mouth. Describing his experience with sharks, Dornellas said: “It is never 100% safe, nothing guarantees your safety when you’re swimming with predators." In Florida it is common for sharks to be found with hooks in their mouths due to fishermen catching them for sport then releasing them with the hook still intact.
