WATCH: 'Biggest great white ever filmed' found off Mexican coast

It's been a helluva summer for shark stories.

In July, a pro surfer was attacked by a shark on live TV in South Africa and — somehow, thank goodness — came out completely unscathed. Mick Fanning, just minding his own business while waiting for a wave during a surf competition, became an Internet legend by apparently punching the shark, getting away and living to tell about it.

Now, we have new video of what's believed to be the biggest great white shark ever filmed.

Mauricio Hoyos Padilla, a shark researcher who was working on a project in 2013 near Guadalupe Island off the Mexican coast, posted video to his Facebook page this week of Deep Blue, a 20-foot female great white shark who's estimated to be about 5,000 pounds and 50 years old.

Here's the video Padilla posted this week, the second of two Deep Blue videos:

If that video gives you the chills, now take a look at this one from June in which a diver is sticking out of the cage and gives the shark a high five (unfortunately, for some reason that one can't be embedded from Facebook so you gotta click the link — sorry).

Holy shark.

Padilla is encouraged by Deep Blue's size and predicted age, because he takes it as a sign of conservation efforts working in the wild. We're all for preserving wild life, so let's hope Deep Blue continues to live a happy life and keeps its feasting to only seals.
