Her name is Deep Blue and, at an estimated 20 feet long and possibly still growing, she's widely considered to be among the largest great white sharks ever caught on camera. It's thought that she could be more than 50 years old.

Mauricio Hoyos Padilla, a shark conservationist working for Discovery's "Shark Week," shot jaw-dropping footage of the massive creature off Mexico's Guadalupe Island in 2013. In the video, the gargantuan creature swam up to the crew's dive cage and poked around curiously before disappearing back into the blue.
Researchers managed to affix a tag to Deep Blue during their expedition. The tag is a scientific device that transmits the shark's depth, location and other data to help researchers better understand the animal's behavior and movement.
Deep Blue swam back into the spotlight again in early 2019 off the coast of Hawaii, where she was spotted by a National Geographic documentary crew as she feasted on a whale carcass.
The underwater footage shot by photographer Mark Mohler showed marine biologist Andrew Gray and fellow photographer Kimberly Jeffries swimming just feet from Deep Blue, cameras in hand as they captured rare footage of the creature.

"I was thinking, 'What in the world is this?' Because it was way bigger than any shark I'd expect," Gray said of the encounter.

Based on the appearance of the shark's stomach, the crew also posited she could be pregnant -- though the sperm whale feast could also be responsible for her enlarged stomach.
"We had [identification] shots and video and it was more than enough to present to at least the scientific community for identification," Jeffries explained, adding that authorities agreed that the massive shark pictured was likely Deep Blue.
In total, the crew spent three days observing Deep Blue and other mature female great whites who dropped by to feed on the whale carcass. Jeffries told National Geographic that wind and water conditions were perfect for shooting crystal-clear footage of the sharks.

That encounter is detailed in an encore presentation of "World's Biggest Great White?" on Friday, August 2, at 8/7c on Nat Geo WILD.
While Deep Blue's theoretical journey from Guadalupe Island to Hawaii might seem like a long way for a shark to travel, the creatures have been known to traverse entire oceans. Scientists in the early 2000s tracked one great white's 12,400-mile journey from South Africa to Western Australia and back.
