Diagnosis |
Diagnosis: Characterized by having membranous, digitate posterior margin on scales; snout shorter than eye diameter; slender maxilla and weakly curved ventrally at posterior tip, partially or completely concealed; poorly developed adipose eyelid as rim around eye; preorbital weakly concave on anteroventral edge (Ref. 90102). Description: No teeth in lips or on palatines, but vomer and tongue dentate; preorbital margin scaly, bent, the notch and serrations become obscured with growth (Ref. 4393). First dorsal fin with 4 spines, second dorsal fin with 1 spine and 8 soft rays; anal fin with 3 spines and 9 soft rays; pectoral fin with 18 rays (Ref. 4393). Scales on lateral line 38-42; scaly process at 1st dorsal fin base 4.2-5.0 times in predorsal distance; pectoral axillary scale 3.2 times in ead length (Ref. 4393, 4967). Colouration: Bluish brown or green dorsally; flanks and abdomen silvery; dusky spots on upper row of scales, giving indistinct longitudinal stripes (Ref. 9812). Dorsal and upper lobe of caudal fin with dark-blue tip; anal, pelvic, and pectoral fins yellow; pectoral fins also with dark blue spot dorsally at origin (Ref. 9812). |
