Lecophores that develop from melanophores. Melanoleucophore are located at the margin of the dorsal fin, in the dorsal and ventral lobes of the caudal fin. Melanoleucophores lack pterdines and carotenoids; exhibited variably shaped organelles distinct from iridophore reflecting platelets and melanosomes and have crystalline Beta-guanine. Melanoleucophores express tyrosinase related protein 1b and purine nucleoside phosphorylase 4a. Immature cells may contain melanin.
