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.

chromatophore

The beginning of this stage was marked by chromatophores becoming visible in unstained embryos (Fig.
In addition, the response to neural stimulation of melanophores and leucophores is opposite: whereas in melanophores the action of neurotransmitters induces the rapid aggregation of melanosomes (and hence fading of the black coloration), in leucophores it induces the dispersion of pigment (whitening), and because the melanophores and leucophores that form chromatophore units may be innervated by the same fibers, this opposite response occurs simultaneously.

Preflexion and flexing blue marlin also formed single-species clusters owing to the pattern of a single, pointate chromatophore in each of lower jaw grid cells 4 and 6, but without any other pigment (except occasionally in grid cell 12 or 13).

The V-shaped anterior bifurcation of the stripe is not apparent anteriorly, but each arm of the bifurcation is bordered dorsally by a dark chromatophore band, and there is a narrow stripe of such chromatophores from the dorsal margin of the pectoral fin base across the opercle to just below the posterior margin of the eye.
Muscles around each chromatophore constrict or expand the cell--when constricted, skin color lightens, when expanded color darkens.
