Watch as an octopus and a crab engage in a game of deadly cat-and-mouse with each other. The action was captured in Rose Bay, located in Sydney, Australia.
The octopus can move in any direction by using water, contracting its muscles, and then expelling the water through a siphon. This allows it to pursue the crab.
It reaches out with its elegant tentacles, grabs the crab, and then brings it back down into the water. Octopuses are able to penetrate the tough shells of crabs, a primary component of their diet, thanks to the sharp beaks on their mouthparts.
