Cells containing pigment that can disperse or concentrate, thereby changing the tint of the organism in which they lie, are known as chromatophores.
In fish, amphibians and reptiles, the pigment of these chromatophores (Greek: chroma, colour: pherein, to bear) can be aggregated or dispersed within the cell, so that the pigment of each chromatophore covers a smaller or larger area of the skin surface.
Such intracellular re-arrangement of the pigment takes place as an adaptation. Chromatophores in the skin of a squid. Chromatophores are pigment-containing and light-reflecting cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods.
Mammals and birds, in contrast, have a class of cells called melanocytes for coloration. Brown FA Jr, Edeströn HE () Dual control of certain black chromatophores of Crangon.

Chromatophores are pigment-containing and light-reflecting cells found in amphibians, fish, reptiles, crustaceans, and are largely responsible for generating skin and eye colour in cold-blooded animals.
Some species can rapidly change colour so as to keep in camouflage, or to do this by moving pigment and reflective plates in chromatophores. The chromatophore system of cephalopods. their richness may depend from the relative complexity of the part of the ''brain'' that takes the ''higher'' neural control This book fills that Author: B.

Arrangement of chromatophores in amphibian skin, called the dermal chromatophore unit. The unit consists of xanthophores, which give yellow, orange, or red coloration, the iridophores, which reflect light and cause bright colors, and the basal melanophores, which have dendritic processes that extend between the xanthophores and the iridophores.

These chromatophores produce red and yellow pigments known as pteridines. These may vary in color from pure yellow to pure red, as well as intermediate shades.
Xanthophores possessing a predominantly red coloration are referred to as erythrophores. Xanthophores also retain yellow to reddish pigments contained in the diet in the form of carotenoids. directly in the control of chromatophores because the neuropil is continuous with that of the LBL, and because stimulation of the median basal lobes produces chromato.
Creatures like octopi with a highly refined chromatophore control system can mimic the color and texture of their environment remarkably well; this camouflage technique is used to hide from predators and also to pursue unsuspecting prey.
Photosynthetic bacteria also use chromatophores, to help them produce energy. Chromatophore, pigment-containing cell in the deeper layers of the skin of animals. Depending on the colour of their pigment, chromatophores are termed melanophores (black), erythrophores (red), xanthophores (yellow), or leucophores (white).
The distribution of the chromatophores and the pigments. Abstract. Rapid color changes of amphibians are mediated by three types of dermal chromatophores, xanthophores, iridophores, and melanophores, which comprise a morphologically and physiologically distinct structure, the dermal chromatophore unit.
Xanthophores, the outermost element, are located immediately below the basal by: Transitional chromatophores are significantly smaller than either yellow or dark ones (transitional versus yellow, P = × 10 −7; transitional versus dark, P = × 10 −4; n = 70 yellow Cited by: 8.
In cephalopods and some fish and reptiles, chromatophore state is under direct nerve control from the visual system, whereas in many other animals it is guided by hormones.
A wide range of work on Uca crabs and other crustaceans shows a chromatophore response at least partly based on eyestalk (sinus gland) produced hormones (e.g. [ 25 ]).Cited by: The first half of the ovarian cycle is the follicular phase shown in Figure Slowly rising levels of FSH and LH cause the growth of follicles on the surface of the ovary.
This process prepares the egg for ovulation. As the follicles grow, they begin releasing estrogens and a low level of progesterone. Progesterone maintains the Author: Charles Molnar, Jane Gair, Molnar, Charles, Gair, Jane. Tool use. Another example of cephalopod intelligence is the communication that takes place between the more social species of squid.
 Some cephalopods are capable of rapid changes in skin color and pattern through nervous control of chromatophores.  This ability almost certainly evolved primarily for camouflage, but squid use color, patterns, and flashing to communicate with one another.
The photos in this post are of the same animal seen in the previous one, all taken as I watched a Giant Cuttlefish produce a long sequence of color changes inside a shallow cave. I’m continuing this theme because a few days after that post, a new article about cephalopod color change came out.
The article, by Leila Deravi and her co-authors, delves into the internal structure of one part of. The chromatophores receive only nerve impulses, and there is no evidence that they are influenced by hormones.
The chromatophores are ultimately controlled by the optic lobe of the brain under the influence of the eyes. Two consequences follow from the fact that cephalopod chromatophores are under the direct control of the brain.
Les chromatophores sont des cellules pigmentaires du derme. Il en existe de plusieurs sortes, chacune responsable d’une couleur.

In terms of orientation, the mouth is to the left of this figure (the beak and lip are labeled,) the supraoesophageal mass is towards the top of the image, and the suboesophageal mass is towards the bottom of the image.
the possibility of the systems that control.There are about species of cephalopods (including the cuttlefishes, squids, octopods, and the chambered nautilus) living throughout the seas of the world. They are considered to be the most highly evolved marine invertebrates and possess elaborate sense organs, large brains and complex behavior.
