The boy's father, Shaun Moore, posted the video to Twitter.

The pair were surfing off New Smyrna Beach, a coastal community in South Florida when it happened.

When slowed down, the video clearly reveals the shark's fin swiping the board.

Moore said he believes it was a blacktip shark that was involved in the close call.
