Responses of the white chromatophores of Palaemonetes pugio (A) and Palaemonetes paladosus (B) to background changes. Circles, black to white; dots, white to black. on a black background (dots) and dispersed when prawns were placed on a white background (circles). No species difference in rate of white pigment dispersion or concentration was evident. The white pigment of neither species was maximally dispersed on a white background. Responses of white chromatophores to illumination One hundred prawns of each species were selected from the stocks and separated into 10 groups. Five lots of each species were placed in white enameled pans and the remaining groups were placed in black enameled pans. One white and one black pan for each species were then placed under one of the illuminations in the light gradient of 1, 10, 40, 120, and 2000 ft. c. intensity. The latter intensity was obtained with sunlight, the remaining intensities in the light gradient were obtained by placing the pans at appropriate distances from the light sources available in the.
