Just when you thought it was safe to get back in the water, footage showing a six-metre great white shark named 'Deep Blue' swimming off Mexico's Guadalupe Island has emerged.
The video shows Deep Blue, believed to be the world's largest great white, swimming near researchers confined in a steel cage.
The footage, which was reportedly shot in 2013, wasn't released until recently when researcher Mauricio Hoyos Padilla found the recording on his computer, the Daily Mail reports.
Deep Blue appeared last year in a Discovery Channel documentary, and researchers tagged the shark for scientific purposes.
Great whites typically grow to 4.5 metres, and are the largest predatory fish on the planet. Scientists believe Deep blue is at least 50 years old, which is an impressive feat for an animal that commonly falls victim to fishing.
