"We heard a fisherman yell out, 'There's a tiger shark!'" Iacuzzo said. "There was instantly excitement and fear. I've always wondered how I would react. He was bigger than my board."
After she and Parham spotted the animal, Iacuzzo said the shark made several passes near her board while she sat on top of it. It never made contact with her board, but after the shark's third pass -- nearly twenty minutes after he was first spotted -- Iacuzzo wondered whether he was getting a little too curious.
"So that's when I paddled," she said. "When I put my paddle in the water, he backed off."
For the estimated 51 percent of Americans who say they're scared of sharks, the run-in would probably have been terrifying, but Iacuzzo's encounter will be remembered much differently.
"It was the most amazing experience of my life," she said. "My body was shaking. It was amazing."
