The shark in the video below is a 20-foot long great white that was found off Mexico’s Guadalupe Island by Mauricio Hoyos Padilla in 2013, NBC reports. We’re actually looking at a pregnant lady shark swimming around the cage of tiny humans who came looking for such gigantic frightening fish.

As NBC notes, female sharks are usually bigger than males, and they’re rarely seen out in the wild like that. This particular one looks like she would have absolutely no problem eating a full person, like the daring diver in the video.
