This is the stuff of nightmares. Some people were shooting this footage of a crab near the waters of Yallingup, Australia, when all of a sudden an octopus jumped up out of the water and wraps it's tentacles around its prey. After a brief struggle, the octopus eventually drags the crab to a watery grave. Once it has its prey, the octopus will use its beak to puncture the shell of the victim, then it injects it with a paralyzing venom, and then consume it by sucking out the crab's innards.  Yikes!
