To continue the ocean theme I seem to be on with the looser style again. An octopus is a cephalopod mollusk. It has two eyes and four pairs of arms and, like other cephalopods, it is bilaterally symmetric. An octopus has a beak, with its mouth at the center point of the arms. An octopus has no internal or external skeleton allowing it to squeeze through tight places. Octopuses are among the most intelligent and behaviorally diverse of all invertebrates..The sketch is a quick pencil sketch for proportions and then direct to watercolor without ink.
