This is a video of some diver who straps a Go-Pro to a hammerhead shark's fin to capture a first person point of view from the shark's back. How do you attach a Go-Pro to the back of a hammerhead shark? VERY CAREFULLY. Just kidding, this guy goes at it with reckless abandon and almost puts his hand in the shark's mouth. You ever put your fingers in a shark's mouth before? Feel free to leave a one-handed comment telling us all about it.
Keep going for the video, which is available in 4K resolution for ULTRA HIGH DEFINITIONS. Get high and pretend you're Merman!
Thanks to David, who agrees hammerheads would make the perfect giant sharks to ride into battle because you can attach all sorts of laser guns and harpoon blasters to their eye stalks for extra firepower.
