As someone who’s petrified of water, nothing is more terrifying to me than scuba diving into the open ocean. This is something that I literally have nightmares about at least once a week. However, while I thought that nothing could top that on the terror scale, I have just been proven wrong.

The following video is from the helmet camera of a diver in the Gulf of Mexico just off the coast of St. George Island in Florida. Right in the middle of his dive, he spotted a giant great white shark stalking him in the depths. He had no choice but to prepare himself for disaster.

To say this video is terrifying is a bit of an understatement.

Luckily, for whatever reason, the shark turned away at the last minute and returned to the depths. Another moment and this diver would have been toast. Ugh…I hate the ocean.
