The marine research group that shot the shark footage above is calling the star of the video “the biggest shark ever filmed.” The shark featured is a 20-foot-long, 50-year-old great white named Deep Blue, who could easily eat you and your dog for lunch.

Video director Mauricio Hoyos Padilla was part of a group of scientists that filmed Deep Blue back in 2013 for a 2014 Discovery Channel special. For the past few months, he’s been posting never-before-seen footage of Deep Blue on his Facebook.

Padilla works for Pelagios Kakunjá, a conservation group dedicated to understanding the lives of marine top predators like Deep Blue.

The group is raising money to both study and save great white sharks by tagging pregnant females, then learning where their nursery grounds are so they can be protected. Great whites set up nursery grounds close to shore, where babies would otherwise be in constant danger from humans.

In June, Hoyos Padilla posted video that some media thought showed him high-fiving Deep Blue. In reality, he was pushing her away from the cage so she didn’t hurt herself.

National Marine Fisheries Service representative Tobey Curtis explained this action to Newsweek; Curtis says that Hoyos Padilla was clearly trying “to deflect the shark from bumping into the cage or getting entangled in the chains above the cage.”

After hearing about the 18-foot tiger shark that swallowed a 6-foot hammerhead before it was caught by an Australian fisherman, we can’t help wondering if Shark Week is actually this week and no one told the Discovery Channel.deep blue 2
