Allen wrote in the Facebook caption."I didn't see this one until [Ethan] was scrolling through videos!".Commenters on Facebook seemed split between thinking the shot was cool and being scared of how close the shark was to Ethan.The type of shark seen in the video is speculated to be a young spinner shark, a species commonly found off of the coast of South Carolina.They grow to be about six to 10 feet long and 120 pounds, but are not considered a threat to humans
