YouTube user Scott Murray had the brilliant idea to attach a GoPro camera to a crab net before casting it to the ocean floor, and was "surprised by what actually goes on down there." 

Spoiler alert: it's really not all that surprising. There are crabs. There are fish. There is an admittedly cool stingray cameo. And if you make it all the way through, you'll even see a dolphin. 

Still, this is a pretty cool perspective on the sea life that comes out when we drop in a freshly-baited net.
