    How does an octopus move?

    A:

    An octopus uses several methods to move through the ocean. An octopus in a hurry uses jet propulsion by rapidly contracting its water-filled mantle, the muscular sac that encloses its gills and body organs. The contracting mantle forces water rapidly through a funnel at its base, propelling the octopus in the opposite direction. Slower movement is achieved by using all eight limbs to maneuver along the sea bottom or around obstacles.
