The cuttlefish is a type of mollusc, capable of changing its skin color at will. It uses this color-change to communicate to other cuttlefish and camouflage themselves from predator and prey. It is among the smartest of invertebrates. The eyes are highly developed, without a blind spot. Scientists believe an unborn cuttlefish starts observing its surroundings while still in the egg and the prey it sees at this stage is the prey it will prefer as an adult.
