The cuttlefish changes shape, sixe, color, and pattern at will. But how? Skin cells. In layers of yellow, red and brown. Pigment cells are attached to muscels and the muscels can pull the pigment cell out into a little disk of color and when the muscels let go it just, "Boink" disapears really fast. Scientists call it electric skin because it is really quick. A bottom layer of skin cells reflect light to produce blue, green, and pink. At a white base, and the cuttlefish pallet is complete.

They put a wind up plastic fish into a cuttlefish tank and then a little bit later they dropped a real fish in. The cuttlefish realized the toy didn't taste good but it found out that the toy resembles food so it tried the the real fish. They soon put a real fish in a jar. Every time the cuttlefish struck the jar, they would drop a real fish in. The cuttlefish would quickly learn this trick and keep hitting the jar. They are quick learners.
