Body Coloration Characterization and Proteomic Analysis of Diurnal Color Variation in Farmed Larimichthys crocea [PDF]

Animals
The large yellow croaker (Larimichthys crocea) is an economically significant aquaculture species in Asia, with skin coloration being a key quality attribute affecting consumer choice and commercial value. This study integrated morphological, biochemical,

Colour Confusion: Reviewing Ambiguities in the Identification and Classification of Chromatophore Deficiencies Among Amphibians [PDF]

Ecology and Evolution
The colour of amphibian skin and eyes (retina and iris) is the result of light interacting with cells called chromatophores, primarily xanthophores, iridophores and melanophores, that can be found in various combinations.

A computational pipeline to track chromatophores and analyze their dynamics [PDF]

eLife
Cephalopod chromatophores are small dermal neuromuscular organs, each consisting of a pigment-containing cell and 10–20 surrounding radial muscles. Their expansions and contractions, controlled and coordinated by the brain, are used to modify the animal ...

Cellular and Molecular Basis of Environment-Induced Color Change in a Tree Frog [PDF]

Animals
Background color matching is essential for camouflage and thermoregulation in ectothermic vertebrates, yet several key cellular-level questions remain unresolved.

DNA methylation of the endothelin receptor B makes blue fish yellow [PDF]

Nature Communications
Animal pigmentation is essential for concealment and communication in nature. Though selection acts on the phenotypes of an organism, these traits are often resolved to genes that shape pigmentation in populations.

Pigment granule architecture varies across yellow, red, and brown chromatophores in squid Doryteuthis pealeii [PDF]

Scientific Reports
Cephalopods produce dynamic colors and skin patterns for communication and camouflage via stratified networks of neuronally actuated yellow, red, and brown chromatophore organs, each filled with thousands of pigment granules. While compositional analysis

Role Analysis of the scarb1 Gene in the Pigmentation of Neocaridina denticulata sinensis [PDF]

Animals
Body color is a key economic trait for Neocaridina denticulata sinensis, an important ornamental shrimp. Scarb1 may be an important mediator of astaxanthin uptake, changing the shrimp’s body color.

Regulatory and disruptive variants in the CLCN2 gene are associated with modified skin color pattern phenotypes in the corn snake [PDF]

Genome Biology
Background Snakes exhibit a broad variety of adaptive colors and color patterns, generated by the spatial arrangement of chromatophores, but little is known of the mechanisms responsible for these spectacular traits.

It's not easy being green: Comparing typical skin colouration among amphibians with colour abnormalities associated with chromatophore deficits [PDF]

Ecology and Evolution
Amphibians can obtain their colour from a combination of several different pigment and light reflecting cell types called chromatophores, with defects in one or several of the cells leading to colour abnormalities. There is a need for better recording of
