WebJul 6, 2024 · Medaka and zebrafish have four kinds of chromatophores, namely melanophores, xanthophores, iridophores, and leucophores (Schartl et al. 2016). The main pigments in pigment cells are eumelanin (melanophores), pteridines and carotenoids (xanthophores), guanine (iridophores), and uric acid (leucophores). WebChromatophores are cells that produce color, of which many types are pigment-containing 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. gpu instances pricing

The term chromatophore was adopted (following Sangiovanni's chromoforo) as the name for pigment-bearing cells derived from the neural crest of cold-blooded vertebrates and cephalopods. The word itself comes from the Greek words chrōma (χρῶμα) meaning "colour," and phoros (φόρος) meaning "bearing".
