Pigmentation:
Melanophores: A short, V-shaped pattern midventrally beneath pelvic fins, apex pointed forward, melanophores not extending posterior to tip of appressed pectoral fin. A paired series of melanophores along base of anal fin, the posteriormost 1-2 median and more intense than others in series. A short series of melanophores on dorsal surface of gas bladder.
Chromatophores: Internal erythrophores at posterior end of skull around base of vertebral column. Diffuse erythrophores ventrally from lower jaw to gas bladder. A prominent series of orange-red chromatophores internally along top of gut from throat to gas bladder. Erythrophores along base of anal fin and internally on dorsal surface of vertebral centra. A wedge-shaped patch of orange- red laterally on caudal peduncle. Some erythrophores on proximal caudal rays. A series of diffuse xanthophores along posterior part of dorsal-fin base. Some xanthophores on proximal caudal rays. |
