They are also used for research on replicating their camouflage abilities due to the
chromatophore s in their skin, which reflect a
Kaynak: Longfin inshore squidThe skins of cephalopods such as the octopus contain complex units, each consisting of a
chromatophore with surrounding muscle and nerve
Kaynak: CamouflageThis color-changing function is produced by groups of red, yellow, brown, and black pigment ed
chromatophore s above a layer of reflective
Kaynak: CuttlefishThe skin is covered in
chromatophore s, which enable the squid to change color to suit its surroundings, making it practically invisible .
Kaynak: Squid10.5 kg (23 lb) in weight Using cells known as
chromatophore s, the cuttlefish can put on spectacular displays, changing colour in an instant.

Kaynak: Endosymbiotic theoryOmmochromes are also found in the
chromatophore s of cephalopod s, and in spider s. Ommochromes are metabolites of tryptophan , via

chromatophore. The gene was first isolated and
