Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 8; Dorsal soft rays (total): 13; Anal spines: 2; Anal soft rays: 9; Vertebrae: 26. First spine of dorsal fin is the longest. Posterior spine on the lower edge of lachrymal long, 3-3.2 times longer than the first, directed posteriorly and downward. Inner side of the pectoral fin dark, with a large faint light-colored spot all along the length of the central part. Caudal fin with 2 wide, dark transverse bands, one in the center of the fin and the other distal, but tip of the rays are light-colored. Tubular scales in lateral line 20, the last 2 are separated from the preceding ones. Gill rakers of first gill arch 3 + 1 + 10 (Ref. 41473).
