Angry octopus attacks a crab

A Crab spots danger ahead lurking, an octopus camouflage itself like the colour of the seafloor. The crab quickly tries to protect itself by concealing its body under the sand. The octopus rushes at the area where it last saw the crab and using its tentacles it shuffles up the sand revealing the crab beneath the surface. The crab tries to escape but the octopus grabs it instantly. The octopus overpowers the crab by injecting venom inside and the crab body becomes motionless, while the octopus devours it.
