Cytophysiology of fish chromatophores
WebAbstractPigmentation patterning systems are of great interest to understand how changes in developmental mechanisms can lead to a wide variety of patterns. These patterns are often conspicuous, but their origins remain elusive for many marine fish species.

The chemical nature of the very thin reflecting platelets within the motile iridophores of the blue damselfish, Chrysiptera cyanea, was studied by thin-layer chromatography on crystalline cellulose. 2. 2. The platelets are composed exclusively of guanine, as judged by the limits of sensitivity of this method. 3. 3.
