A chilling video has surfaced of a diver being mauled in a savage attack by the world's fastest shark.
Chad Patti and his friend Josh Loucks were spearfishing on New Year's Day when he was attacked by a 10ft shortfin mako shark around 70 miles off of Florida's coast in the US.
Mr Patti, 30, had a GoPro camera strapped to his head at the time of the attack, catching the terrifying encounter on film.
