Key facts about Octopus

• It is a marine mollusk and a member of the class Cephalopoda, more commonly called cephalopods.
• Cephalopoda means “head foot” in Greek, and in this class of organisms the head and feet are merged.
• A ring of eight equally-long arms surround the head. They use their arms to “walk” on seafloor.
• The undersides of the arms are covered with suction cups that are very sensitive to touch and taste.
• The sack-like body is perched atop the head, which has two complex and sensitive eyes, while the mouth is on the underside.
• They have three functioning hearts.
• Two of the hearts work exclusively to move blood to the gills, while the third pumps blood through the rest of the body.
• Their blood is copper-based which is more efficient at transporting oxygen at low temperatures and makes their blood blue in color.
• They are solitary creatures excellent at camouflaging and concealing themselves.
• They are about 90 percent muscle, and because they lack bones, they can fit through very small spaces.
• Their skin contains cells called chromatophores that allow the octopus to change color and pattern.
• They are found in every ocean of the world.
