Épines dorsales (Total) : 12; Rayons mous dorsaux (Total) : 15 - 17; Épines anales: 3; Rayons mous anaux: 7 - 8. Scale rows immediately below lateral line oblique (Ref. 26938). Usual color phase dull silvery, the fins largely gray; no black pigment below upper margin of preopercle; the dorsal and caudal fins of subadults and the back above a line from dorsal base to lower margin of caudal fin are often blackish (Ref. 13442).
Inhabits seagrass beds, sand flats, coral reefs, and wrecks (Ref. 9710). Found in pairs or larger schools (Ref. 3798). Feeds on benthic invertebrates (Ref. 3798). Has been observed to nose into the sand to eat such subsurface invertebrates as peanut worms and heart urchins (Ref. 13442). Marketed fresh (Ref. 3798).
Oviparous, distinct pairing during breeding (Ref. 205).
