It has two eyes and four pairs of arms and, like other cephalopods, it is bilaterally symmetric. An octopus has a hard beak, with its mouth at the center point of the arms. An octopus has no internal or external skeleton (although some species have a vestigial remnant of a shell inside its mantles), allowing it to squeeze through tight places. Octopuses are among the most intelligent and behaviorally flexible of all invertebrates. The octopus inhabits many diverse regions of the ocean, including coral reefs, pelagic waters, and the ocean floor. It has numerous strategies for defending itself against predators, including the expulsion of ink, the use of camouflage and deimatic displays, its ability to jet quickly through the water, and its ability to hide. An octopus trails its eight arms behind it as it swims. All octopuses are venomous, but only one group, the blue-ringed octopus, is known to be deadly to humans. Around 300 species are recognized, which is over one-third of the total number of known cephalopod species. The term 'octopus' may also be used to refer specifically to the genus Octopus.Approx. image size 19, 6 x 12, 6/24, 8 x 17 cm.
