New footage has emerged of a six-metre-long great white shark named "Deep Blue", believed to be the largest of its kind in the world.

The footage was captured by shark researcher Mauricio Hoyos Padilla off Mexico's Guadalupe Island in 2013, but wasn't released until now because he had only recently found the recording on his computer.

The video shows the enormous apex predator swimming near researchers in steel cages, with one bold enough to be swimming outside the protection of the protective metal bars.

At the end of the clip, the curious shark bumps into one of the cages with its nose, showing off it's rows of razor-sharp teeth to the camera below.

This is the second clip of Deep Blue that Padilla has released this summer. The first video was released in June and shows a research touching the shark's fin.

The massive predator was also featured last year in a Discovery Channel documentary, when researchers tagged the gigantic animal.

In the documentary, the narrator explains that large, vertical slashes on Deep Blue's left flank could be the result of fights with sharks or mating.

The fish has a large, gaping hole on her right trunk and her dorsal fin and tail appear to be scraped and damaged.

After researchers tagged the beast, she led them to an elephant seal colony - a typical meal for an adult great white shark.

Divers and shark enthusiasts from across the world travel to Guadalupe to view great whites in the island's water.
