While snorkeling with 6 Caribbean reef sharks, one shark decided to get too close for comfort to one of the divers. The diver had to resort to extreme measures to prevent a brutal attack.
The video shows the diver apparently taking a selfie underwater when one of the sharks starts to swim too close. At this point, most people would probably freak out and cause a feeding frenzy, but not this guy.
With an open hand, he slaps the shark on its nose and thwarts it away. After that, however, the surrounding sharks became very excited so the diver had to be extra careful with his movements. They were able to finish their dives with no injuries.
