Max length : 32.0 cm TL mâle / non sexé; (Ref. 43588); 38.0 cm TL (female); poids max. publié: 456.14 g (Ref. 102462)
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 79 - 92; Épines anales: 0; Rayons mous anaux: 65 - 72; Vertèbres: 38 - 39. Caudal fin double truncate (Ref. 27363). Almost wholly ambicolorate, the blind side is darkly pigmented except for the anterior portion of the body which has dark pigments only on the opercle, subopercle, a small region adjacent and dorsal to the head, and the distal half of the pectoral fin; two lighter pigmented areas were present on the unpigmented dorsal region of the head. The blind side had one of the 3 typical ocelli (upper one) in the same position with that of the ocular side (Ref. 34245).
