Chromatophore

Chromatophore (pronunciation: kroh-MA-toh-for) is a cell or plastid that contains pigment.

Etymology

The term "chromatophore" is derived from the Greek words "chroma" meaning color and "phore" meaning bearer.

Definition

A Chromatophore is a type of cell that produces and stores pigment. These cells are responsible for the coloration of many animals, particularly reptiles, fish, and cephalopods. Chromatophores are classified into various types based on the color of pigment they contain, such as melanophores (black/brown), erythrophores (red), xanthophores (yellow), and leucophores (white).

Function

Chromatophores are primarily used for camouflage, communication, and protection from UV radiation. They achieve this by expanding or contracting to change the color and pattern of the animal's skin. In some species, such as the cuttlefish, chromatophores can create complex and rapidly changing displays.
