This process, known as physiological colour change, is most widely studied in melanophores, since melanin is the darkest and most visible pigment. In most species with a relatively thin dermis, the dermal melanophores tend to be flat and cover a large surface area. However, in animals with thick dermal layers, such as adult reptiles, dermal ...
Fish and frog melanophores are cells that can change colour by dispersing or aggregating pigment-containing melanosomes. A melanosome is an organelle found in animal cells and is the site for synthesis, storage and transport of melanin , the most common light-absorbing pigment found in the animal kingdom .
Close-up of fish melanophores. Fish coloration is produced through specialized cells called chromatophores. The dermal chromatophore is a basic color unit in amphibians, reptiles, and fish which has three cell layers: "the xanthophore (contains carotenoid and pteridine pigments), the iridophore (reflects color structurally), and the melanophore (contains melanin)".

Fish and frog melanophores are cells that can change colour by dispersing or aggregating pigment-containing bodies. Chromatophores are special pigment-containing cells that may change their size, but more often retain their original size but allow the pigment within them to become redistributed, thus varying the colour and pattern of the animal.
Chromatophores are color pigment changing cells that are directly stimulated by central motor neurons. They are primarily used for quick environmental adaptation for camouflaging. The process of changing the color pigment of their skin relies on a single highly developed chromatophore cell and many muscles, nerves, glial and sheath cells.
English: 7x speed timelapse video of fish melanophores responding to 200μM adrenaline. Melanophores are cells found on the skin and/or scales of many aquatic vertebrates including fish and amphibians. They are large cells which contain many dark pigment particles called melanosomes, made dark by the presence of the pigment melanin.
English: Melanophores with dispersed melanosomes appear dark; with aggregated melanosomes they appear light. This is a mechanism of colour change in fish and frogs. This is a mechanism of colour change in fish and frogs.
The peacock flounder can change its pattern and colours to match its environment. A soldier applying camouflage face paint; both helmet and jacket are disruptively patterned . Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them ...
