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.
