The formation of the complex pattern is influenced by the neurons and two lobes of the cuttlefish brain. Studies indicate that the cuttlefish skin contains approximately ten million color cells, the color cells function in a pattern, when some are on other color cells are off. These alternative functions of skin color cells enable them to create a pattern required to confuse their predators. Besides, cuttlefish possess a pigmented organ known as the chromatophore. When it is stimulated the chromatophore produces black, red, brown and yellow colors (Mäthger et al. 2005). A band of muscles that originate from the chromatophores allows the cuttlefish to change the color pattern according to its surrounding by relaxing the muscles to alter the different color layer (Chiao and Halton

    The experiment was done by observing the Himantura leopard and Dasyatis Americana interactions with a school of fishinside a 760,000 gallon tank at the Adventure Aquarium for 90 minutes. There were two Himantura leopard organisms and approximately five to six DasyatisAmericana. A school of fish was observed as three fishes that are approximately three inches away from each other. When either species of stingray came within five inches of the described school of fish, it was marked down if any of the fishes in the school separated from the school by swimming in an opposing direction of the other fishes of the school. If a fish separated from the school, it was marked down as “break apart” for the specie of stingray that caused the separation.
