“It was the kind of force that I felt would normally knock me over but it didn’t,” said Bowden.

At the time of the attack, Bowden says he was waist deep and didn’t realize he had just been bitten by a shark.

“I was hoping it was not a shark, but I knew that was a possibility. Something did not feel right. It didn’t feel like I got a bite, but it did not feel normal either.”
