Octopus The octopus ( /ˈɒktəpʊs/; traditionally, plural: octopuses, see below) is a cephalopod mollusc of the order Octopoda. Octopuses have two eyes and four pairs of arms, and like other cephalopods they are bilaterally symmetric. An octopus has a hard beak, with its mouth at the center point of the arms. Octopuses have no internal or external skeleton (although some species have a vestigial remnant of a shell inside their mantle), allowing them to squeeze through tight places. Octopuses are among the most intelligent and behaviorally flexible of all invertebrates. Big Blue Octopus,Marine,Octopus,Octopus cyanea,Red Sea,Sea Click/tap to enlarge Species intro
