Diver Puts Sharks Into A Trance

A diver puts a Caribbean reef shark into a trance using just his hands. British underwater photographer Simon Enderby captured the amazing moment during a routine feeding dive off the coast of the Bahamas. One diver can be seen reaching out to touch the shark, triggering receptors in its nose and inducing a state of immobility. The shark then rests vertically in the palm of his hand, before snapping out of the trance and swimming away. The technique - called tonic immobility - is widely used by shark handlers and doesn't harm the shark.
