| Definition: |
Lecophores that develops from xanthophores. Xantholeucophores are located on the anal fin. Xantholeucophores contain round organelles carotenoid vesicles containing yellow/orange pigment as well as irregular organelles indistinguishable from pterinosomes, which contain yellow or colorless pteridines. During development white pigmentation surrounds a yellow-orange center, gradually increasing until whole cell appears white. Xantholeucophore express aldehyde oxidase 5 and purine nucleoside phosphorylase 4a. These cells most closely resemble the leucophores of other teleost.
