This beach video shows an Octopus snaring a crab with an ultra-fast move. It’s so fast that it startles the camera-person who starts shaking while trying to find the two after the initial grab. It’s a really interesting video of how quick an octopus can be in nature. There’s not really much of a “vs” battle as the octopus takes the crab totally by surprise.
