Short description Morphology | Morphometrics

Dorsal spines (total): 5; Dorsal soft rays (total): 34-39; Anal spines: 3; Anal soft rays: 25 - 29. The ocular band of adult specimens with a series of dark vermiculations (Ref. 1602). Adults (above 20 cm) yellowish silvery or dusky, dark bar through eye and another bar just behind head. Occasionally with a few small, scattered black spots on body. Median fins yellowish, with black margins posteriorly. Pelvic fins black. Small juveniles reddish brown, with irregular black spots and blotches and small, white (black-edged) ocelli on body. Small black spot at base of last 3 dorsal- and anal-fin rays. Caudal fin transparent except for base, which is reddish brown. Body orbicular and strongly compressed, its depth more than twice length of head and 0.9 to 1.4 times SL. Head length 3.4 to 3.8 times SL. Snout profile of large adults (above 40 cm total length) concave, with bony swelling between eyes. Interorbital width 38 to 48% head length. Jaws with bands of slender, flattened, tricuspid teeth, the middle cusp about twice length of lateral cusps. No teeth on palatines or vomer. Five pores on each side of lower jaw. Preopercle smooth. Opercle without spines (Ref 43039).

Biology     Glossary (e.g. epibenthic)

Live in shallow protected coastal waters to deep, somewhat silty habitats. Often with deep shipwrecks (Ref. 48637). Adults are found singly or in small groups and occasionally in large schools in some areas. Juveniles occur singly or in small groups among mangroves and inner sheltered lagoons while adults move out to open waters over sandy areas of deep lagoons, channels, and seaward reefs to a depth of at least 30 m. Feed on algae, invertebrates and small fishes (Ref. 89972).
