Octopus Coloring Pages: A real octopus is a highly interesting sea animal that has a rounded head and eight long, slender arms each of which is lined with hundreds of cups. Its body is tender and can easily flatten to pass through the narrow passages with relative Case and facility. Many of the arms which are jointed and flexible sway gently in the water and any vibrations are detected instantly. The skin of the octopus has the ability to discharge colours and form, through the use of cells in its body known as chromatophores, either to hide from predators or to signal. It has a beak like mouth, in the midst of these tentacles, which it uses to capture prey and given that it is a highly intelligent and problems solving animal, such a predator is likely to be unique.
