The new approach, by contrast, is built on the unusual characteristics of certain chromatophore or pigment-bearing cells, called erythrophores, from Siamese fighting fish.
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).
Twenty-four hours later, these animals were clearly infected, showing fragile antennas and soft cuticle as well as chromatophore expansion along the whole surface of the body, particularly at the tail fan (telson and uropods).
Morphological characters associated with metamorphosis included a flexed notochord, fully developed fin rays, a pronounced chromatophore at the base of the caudal fin, and well developed teeth.

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.
White or blue light prompts the pale skin's tiny quick-change color organs, or chromatophores, to expand, creating waves of yellows and browns.
