FORGET the film Sharknado. That was just Hollywood hype.

The reality of sharks going completely berserk is far scarier.

Incredible footage captured off the coast of Mexico will make you think twice about plunging into the ocean.

The video, posted three days ago, shows a great white, about 4 metres long, apparently smashing through the metal frame of a diving cage.

That’s right. A metal cage. You know, the type that’s meant to protect humans from becoming bait!

Onlookers watch in disbelief and react the only way they can: “Oh my God”

Then someone asks: “Is there anybody in there?”

“Nobody’s in there,” someone replies.

Terrifying. The Great White went berserk.

“Somebody’s in the cage.”

What happens next is just crazy.
