Deep Blue, believed to be the largest great white shark ever filmed, was found near Mexico’s Guadalupe Island, a volcanic island that lies approximately 150 miles off the west coast of Mexico’s Baja California Peninsula.

Footage of Deep Blue, approximately 50 years old and pregnant, was captured in 2013 for a feature on a Discovery Channel documentary during Shark Week last year.

The new footage was uploaded to Facebook on Monday by shark researcher Mauricio Hoyos Padilla in a bid to protect the giant fish.

Awe-inspiring and imposing, her length, 19½ feet (6 metres), almost matches that of the research crew’s 22-foot boat. Vertical slashes on her left flank “could be from fights with sharks or mating scars,” explains the Discovery Channel.
