Full Answer

An octopus also has the ability to release a cloud of black ink to block a pursuing predators view. The black ink cloud released by octopuses includes the added benefit of containing a substance that reduces the sense of smell of any predators giving chase. Because they lack bones and have soft bodies, octopuses are also able to fit into small cracks and hide when being chased and can even sacrifice one of their arms if needed in order to escape the grasp of a hungry predator.

  • Q:

    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.
