The class Cephalopoda consists of the squids and octopuses. The name means head-foot and they have large heads with a mouth and horny beak, surrounded by muscular tentacles, sometimes with suckers or hooks. The shell may be reduced or absent. They have large eyes and part of the mantle forms a muscular siphon through which water is forced to provide jet propulsion. Some can change color by way of camouflage and several extrude a cloud of ink for protection. They are all marine and many are big, swift and intelligent.
