While the iridophores in Anolis appear to remain passive in the color changes of this animal, those in other species (4,6,19,21,43,49) are reported to undergo changes that are responsible for a color shift through the entire spectrum . The ultrastructural manifestations, mechanism, and generality of these changes have not been explored .…”

“…Whereas melanophores, iridophores, and xanthophores are widely distributed among poikilothermic vertebrates (fishes, amphibians, and reptiles), leucophores and cyanophores have been found in only a few fish species (5)(6)(7). Among the fish species, medaka has four types of pigment cells, including leucophores, melanophores, xanthophores, and iridophores.…”

Animal body color is generated primarily by neural crest-derived pigment cells in the skin. Mammals and birds have only melanocytes on the surface of their bodies; however, fish have a variety of pigment cell types or chromatophores, including melanophores, xanthophores, and iridophores. The medaka has a unique chromatophore type called the leucophore. The genetic basis of chromatophore diversity remains poorly understood. Here, we report that three loci in medaka, namely, leucophore free (lf), lf-2, and white leucophore (wl), which affect leucophore and xanthophore differentiation, encode solute carrier family 2, member 15b (slc2a15b), paired box gene 7a (pax7a), and solute carrier family 2 facilitated glucose transporter, member 11b (slc2a11b), respectively. Because lf-2, a loss-of-function mutant for pax7a, causes defects in the formation of xanthophore and leucophore precursor cells, pax7a is critical for the development of the chromatophores. This genetic evidence implies that leucophores are similar to xanthophores, although it was previously thought that leucophores were related to iridophores, as these chromatophores have purine-dependent light reflection. Our identification of slc2a15b and slc2a11b as genes critical for the differentiation of leucophores and xanthophores in medaka led to a further finding that the existence of these two genes in the genome coincides with the presence of xanthophores in nonmammalian vertebrates: birds have yellow-pigmented irises with xanthophore-like intracellular organelles. Our findings provide clues for revealing diverse evolutionary mechanisms of pigment cell formation in animals.

“…A similar opposite response In two chromatophores has been demonstrated in vi tro on isolated scales of Fundulus to exogenous epinephrine (Odiorne, 1933) and on those of the medaka to potassium ions (Miyoshi, 1952).…”
