A great white shark measuring by cage divers near Mexico.

The massive predator which is estimated to be more than 20 feet lonk was spotted in the waters near Mexico’s Guadalupe Island.

The massive shark, who is estimated to be around 50 years old, is believed to be one of the largest great white sharks ever seen.

She was featured last year in a Discovery network documentary after local researcher Mauricio Hoyos Padilla managed to tag her.

But Hoyos has posted new footage of Deep Blue that shows her come nail-bitingly close to a cage diver, reports Grind TV.

Hoyos posted the video on Facebook, under the title, “I give you the biggest white shark ever seen in front of the cages in Guadalupe Island… DEEP BLUE!!!”

The unbelievable footage shows the mammoth shark swimming around the cage, seemingly ignoring the divers in a roof-less steel cage.

One brave diver decides to swim out of the cage and reaches out to touch the shark.

The clip has been viewed more than 1.5million times and has been shared 29,000 times since it was posted on Facebook.
