chromatophore

 [kro-mat´o-for]
any pigmentary cell or color-producing plastid.

chro·mat·o·phore

(krō-mat'ō-fōr),
1. A colored plastid, due to the presence of chlorophyll or other pigments, found in certain forms of protozoa.
2. Melanophage; a pigment-bearing phagocyte found chiefly in the skin, mucous membrane, and choroid coat of the eye, and also in melanomas.
3. Synonym(s): chromophore
4. A colored plastid in plants, for example, chloroplasts, leukoplasts, etc.
[chromato- + G. phoros, bearing]

chromatophore

A pigment-containing cell.

chromatophore

  1. (also called chromoplast) a pigmented PLASTID of plant cells which may be green due to the presence of chlorophyll or differently coloured because of the presence of CAROTENOID pigments. CHROMATOPHORES are often CHLOROPLASTS in which the pigment has broken down, as in the ripening of fruit.
  2. (in animals) a cell with pigment in the cytoplasm which can be dispersed or concentrated so changing the colour of the animal as a whole. Animals with this characteristic include frogs, chameleons, cephalopods.
  3. (in photosynthetic bacteria and CYANOBACTERIA) a membranous structure carrying photosynthetic pigments.

It wasn't until 2013 that biologists discovered that iridophores also played a role.
This patterning leads to chromatic components such as the dorsal stripe, arm spots, and the iridophore splotches located on the mantle, fin, and head.
The bluish coloration of the integument in teleosts is usually generated by light-reflecting chromatophores, called iridophores, that contain very thin light-reflecting platelets in the cytoplasm.
Reflection and polarization of incident light by squid iridophores is accomplished by layers of intracellular platelets that are positioned parallel to each other (5).
Fishes commonly present two main types of light scattering/reflecting chromatophores; i.e., leucophores and iridophores. Leucophores scatter light of wide wavelengths in all directions, they appear whitish when illuminated, and the light reflection is diffuse.
Its bluish-pigmented cells, iridophores, reflect light through yellowish cells (xanthophores).
The body is almost solid yellow at 4 DPH, at which time eye pigmentation first appears and the iris iridophores reflect silver.
Chromatic expression is achieved by pigmented chromatophores, underlying reflective leucophores and iridophores, and polarizing elements (Mirow, 1972a, b; Messenger, 1974; Packard and Hochberg, 1977; Cloney and Brocco, 1983; Packard, 1988; Mathger and Hanlon, 2007).
Golden epaulettes was a lightened band at the most anterior point of the dorsal mantle that occurred as a result of the contraction of chromatophores (referred to as "Dorsal mantle collar iridophores" by Hanlon, 1988; Hanlon et al., 1994, 1999).
