Diver Mark Rutzen is increasingly making a name for himself across the globe as a man who's willing to get closer to sharks than any other.
The free-diver and former fisherman, who is currently diving off the coast of South Africa with Great Whites, touches and even rides the massive predators - in the wild.
Rutzen says the key to staying alive is a matter of manners.
"You have to introduce yourself to the animal, you can't just go up to it and grab hold of it," he told News Ltd.
"The biggest mistake any free-diver could make would be chasing the animal through the water."
Rutzen says he relies on experience and a "telepathic understanding" to avoid becoming a meal.
