His hallmark is his yellow hood he always wears when diving at the Shark Reef Marine Reserve. He knows more about sharks than anybody I know. Maybe not the hard scientific facts, but he spent his entire life diving in Beqa Lagoon off Fiji spending thousands of hours in the water with bull, tiger, lemon and all sorts of other sharks. He is the one that feeds the acoustic transmitters to the sharks and without his skills and knowledge I would know a lot less about bull sharks.
He truly loves and cares about sharks.
