Three set-ups were exposed to different experimental conditions namely: set-up A. under prolonged light: set-up B. under prolonged darkness: set-up C. under normal condition. Observation was done under the dissecting microscope from the first appearance of melanophores until the migration was stabilized. The pattern of differentiation was observed to be the same in all set-ups. only the distribution and the color intensity differred. B was the darkest and C was the lightest. It only showed that light could not, alter the pattern of melanophore differentiation, only the distribution.
