At the time, all sharks eat humans
You might have brushed up on which sharks eat humans and which don’t, but if you’re not fully prepared for what can take place on a dive, that knowledge will go right out the window. While diving 30 to 40 feet underwater, the OP found himself face-to-face with a scary paddlefish shark.
Now, for those of us who are safely on land, we can judge this guy for nearly peeing his pant. Paddlefish sharks feed on plankton, not humans. But when you’re underwater and facing a shark head-on, anything and everything is out to get you. If we were in that guy’s situation, we would’ve probably succumbed to our fear.
