If you have a fear of sharks, this video will be the end of you.
In the clip, marine researcher and avid scuba diver Mauricio Hoyos Padilla leaves his protective cage while shark diving to get up close and personal with Deep Blue, a shark believed to be one of the largest ever caught on film.
The massive great white was recently featured on Discovery's Shark Week.
In an incredibly ballsy move, Padilla approaches the shark and reaches out to give it a high five during a scuba excursion in the waters off of Mexico's Guadalupe Island.
Fortunately, his stunt goes down smoothly, and Padilla emerges triumphant and without injury.
