Shaun Moore, a professional wakeboarder, told People that he and his son Chandler were at New Smyrna Beach, riding the waves for about 15 minutes before Chandler fell off his surfboard. Moore said Chandler told him that something had bumped him off his surfboard. The pair didn't see anything at the time, so they continued surfing.
It was only when Moore took the footage from the GoPro camera attached to his son’s surfboard and posted it on Instagram that commenters pointed out the presence of a shark. Upon closer review, Moore said it was a blacktip shark that struck Chandler’s surfboard.
