Besides the pigment-cells just described, Heincke discovered another kind of chromatophore, which was filled with iridescent crystals.
"chromatophore" or pigment bearing cells, called erythrophores, from Siamese fighting fish, whose response to specific toxic chemicals have been studied in detail by Trempy's collaborator, OSU biochemist Phil McFadden.
He blinks, barely noticing her black bob of hair, chromatophore-tinted shadows artfully tuned around her eyes.
The Sanger sequence data also showed that both A and G alleles were present at this position, as revealed by double chromatophore peaks (8× coverage from four independent DNA extracts).
In addition, the Duke researchers are conducting behavioral experiments to investigate counter-illumination (a form of bioluminescent camouflage) and chromatophore use in cephalopods by placing them in tanks with walls of variable backgrounds and then photographing the body pattern responses.
