Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 19-22; Anal spines: 3; Anal soft rays: 14 - 17; Vertebrae: 25. This species is distinguished by the following characters: dorsal profile moderately convex anteriorly; adipose eyelid well developed, moderate anteriorly, posterior eyelid extends onto eye to rear border of pupil; gill rakers (including rudiments) 6-8 + 15-19 = 21-25; straight part of lateral line with 0-3 anterior scales followed by 27-36 strong, dark scutes; breast completely scaly; vertebrae 10+15; upper jaw with outer row of strong canines widely spaced in adults, and an inner band of small villiform teeth, widest at symphysis; on lower limb of first gill arch jaw with a single row of strong conical teeth widely spaced in adults. Colour in life with adults' head and body silvery olive to iridescent blue-green above, silvery olive to whitish below; small blackish spot, much smaller than pupil diameter, at upper angle of opercle (this spot evident on specimens of about 14 cm fork length); second dorsal fin olive to blackish, the lobe with a white tip (white tip becomes more obvious with increasing size) (Ref. 9894).

Biology     Glossary (e.g. epibenthic)

Inhabit coastal and oceanic waters associated with reefs (Ref. 9283, 58302). Pelagic at 1-96 m (Ref. 58302). Often seen in large daytime schools; solitary at night when feeding (Ref. 90102). Adults are found in coral reefs and are mostly active at night or during twilight periods. During the day they are usually seen milling in stationary aggregations (Ref. 44894); form slow-moving schools in the passes or outside the reef, dispersing at night feed (Ref. 4795). Juveniles may be encountered in estuaries (Ref. 9283, 44894), occasionally entering rivers and penetrating well inland (Ref. 2847, 44894). Feed mainly on fishes, squids and crustaceans (Ref. 9283, Ref. 90102). Caught mainly on hook-and-line; also with gill nets, purse seines, and other artisanal gear (Ref. 9894). Marketed fresh, dried or salted (Ref. 9283) and frozen (Ref. 9987). Consumed broiled and baked (Ref. 9987).
