Mauricio Hoyos Padilla posted the terrifying footage to his Facebook page, showing a diver ‘high-fiving’ a shark named Deep Blue.
The 20ft female Great White is thought to be one of the largest ever seen, and certainly looks ginormous compared to the tiny diver on top of the cage.

‘I give you the biggest white shark ever seen in front of the cages in Guadalupe Island….DEEP BLUE!!!’ Mauricio captioned the video.
In another piece of footage shot for discovery, the same shark can be seen getting tagged, as the crew remark: ‘It’s a lot bigger than a goldfish.’
You can say that again chaps.
The shark is thought to be about 50 years old, and was also heavily pregnant at the time of filming - meaning she was sure to be extra hungry.
That is one seriously brave diver.
