OCTOPUS

An octopus (or octopi, or octopodes) is a cephalopod mollusk in the order Octopoda. It has 2 eyes and eight arms (hence name octo, meaning eight) and like other cephalopods it is bilaterally symmetric. The octopus also has a beak right in the center of the tenticals. The octopus does not have an external or internal skeleton, though some species have shells like the nautilus.
