These dermal chromatophore units (DCU) consist of an uppermost xanthophore or erythrophore layer, then an iridophore layer, and finally a basket-like melanophore layer with processes covering the iridophores. [17] Both types of melanophore are important in physiological colour change.
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)". [5]
Blue-ringed octopuses spend most of their time hiding in crevices while displaying effective camouflage patterns with their dermal chromatophore cells. Like all octopuses, they can change shape easily, which allows them to squeeze into crevices much smaller than themselves.
The pseudopodial process (aka the tanning process) happens slowly in dermal melanocytes in response to ultraviolet light and to production of new melanosomes and increased donation of melanosomes to adjacent keratinocytes, which are typical skin surface cells. Donation occurs when some keratinocytes engulf the end of the melanocyte pseudopodia ...
The brilliant iridescent colors of the peacock's tail feathers are created by structural coloration, as first noted by Isaac Newton and Robert Hooke.. Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination ...
The dermal chromatophore unit includes xanthophores, iridophores, and melanophores, which function together to display or inhibit certain coloring. [5] The movement of melanosomes to melanophore fingers conceals the light-reflecting iridisphore layer, dictating a darker pigmentation at night.
The elongate jewel squid (Histioteuthis reversa), so called because the photophores festooning its body make it appear bejewelled. Diagram of a cephalopod's photophore, in vertical section.
