- Octopus (Wikipedia.org)
"It has two eyes and four pairs of arms and, like other cephalopods, it is bilaterally symmetric. It has a beak, with its mouth at the center point of the arms. It has no internal or external skeleton (although some species have a vestigial remnant of a shell inside their mantles),[3] allowing it to squeeze through tight places.[4] Octopuses are among the most intelligent and behaviorally diverse of all invertebrates."
"They trail their eight arms behind them as they swim. All octopuses are venomous, but only one group, the blue-ringed octopus, is known to be deadly to humans.[5]" 04-16
