Neon-green fluorescence in the desert gecko Pachydactylus rangei caused by iridophores [PDF]
Scientific Reports, 2021 Biofluorescence is widespread in the natural world, but only recently discovered in terrestrial vertebrates. Here, we report on the discovery of iridophore-based, neon-green flourescence in the gecko Pachydactylus rangei, localised to the skin around the

Gene Expression Analysis of Zebrafish Melanocytes, Iridophores, and Retinal Pigmented Epithelium Reveals Indicators of Biological Function and Developmental Origin [PDF]
PLoS ONE, 2013 In order to facilitate understanding of pigment cell biology, we developed a method to concomitantly purify melanocytes, iridophores, and retinal pigmented epithelium from zebrafish, and analyzed their transcriptomes. Comparing expression data from these

Intermediate filaments spatially organize intracellular nanostructures to produce the bright structural blue of ribbontail stingrays across ontogeny [PDF]
Frontiers in Cell and Developmental BiologyIn animals, pigments but also nanostructures determine skin coloration, and many shades are produced by combining both mechanisms. Recently, we discovered a new mechanism for blue coloration in the ribbontail stingray Taeniura lymma, a species with ...

Iridophores as a source of robustness in zebrafish stripes and variability in Danio patterns [PDF]
Nature Communications, 2018 Iridophores interact with other cells to give zebrafish their stripes, but what drives their form shifts is unknown. Here, modelling allows the authors to identify robust cues that may specify iridophore form and to find changes to these cues that likely

Partial Replacement of Fish Meal with Fish Scale Meal Enhances Body Color Brightness and Iridophore Development in Koi (Cyprinus carpio var. koi) [PDF]
AnimalsBody color brightness is a key determinant of ornamental value in koi, yet nutritional strategies targeting structural coloration mediated by iridophores remain underexplored.

Asymmetric Functional Divergence of alx4a and alx4b in Iridophore Differentiation and Cranial Development in Nile Tilapia [PDF]
CellsNeural crest cells give rise to the craniofacial skeleton and multiple pigment cell lineages, yet how duplicated developmental regulators partition their ancestral functions after teleost-specific whole-genome duplication remains unclear.

Frogs have layers: a comparative histological study of colour polymorphism in Oophaga poison frogs [PDF]
PeerJBackground Colour polymorphism in aposematic species is often associated with ecological divergence and predator selection. In amphibians, colouration is achieved through the chromatophore unit, a layered structure of pigment-containing cells ...

Inconspicuous breeding coloration to conceal eggs during mouthbrooding in male cardinalfish [PDF]
iScienceSummary: Animals exhibit colorations optimal for their niche, which hides their existence from other organisms. In Apogoninae fishes, the father broods their egg inside their mouth.
