Video Footage May Reveal the Largest Great White Shark Ever Caught on Camera "Deep Blue" is 20 feet long and 5,000 pounds.

 -- A new video showing a pregnant, 20-foot-long great white shark may be the largest of its kind ever to be caught on camera.

The estimated 50-year-old shark, nicknamed "Deep Blue," was discovered near Guadalupe Island by shark researcher Mauricio Hoyos Padilla in 2013.

It’s unclear why he waited two years to post the video, and he could not be reached to clarify.

The video, titled "Deep Blue (The biggest shark ever filmed) second part," shows Deep Blue circling the cages of researchers in the waters off the Mexican Coast, with one diver swimming outside the bars.
