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

Both males and females have irregular markings on ventral parts of the body; some females have the venter almost immaculate; there is a tendency for melanophores to concentrate on borders of lips and medial-anterior part of throat, in a heart-shaped pattern.

Females are heavily stippled, whereas males have a very distinctive pigment pattern consisting of abundant melanophores covering the testes dorsally and two dark, inverted triangular patches on the carapace dorsally.
When stimulated by hormones, dark pigments in the melanophores (dark pigmented cells) spread to the top.
They concluded, however, that there was probably no biological difference in the activity of albumin-bound vs albumin-free melatonin because the addition of albumin did not affect the lightening effect of melatonin on melanophores in frog skin.
Pigmented pectoral-fin rays were the dorsalmost rays with evident melanophores and, because pigment appears consistently with development, counts of these rays are presented for specimens larger than 100 mm in standard length (SL) only.
Females also have an oval to lozenge-shaped spot at the central base of their caudal fin, which is often broken up into small spots with a high concentration of melanophores.
Helcogramma steinitzi has melanophores only on the distal half of the anal fin (in the other two species melanophores cover the entire fin) and a narrow interorbital (16.
