S. s. laqueus greyish green with head and body covered with chocolate brown spots; in S. s. stellatus, background color is yellowish. Trailing edges of soft parts of dorsal and anal fins, perimeter of caudal fin and a saddle over the caudal peduncle are markedly paler than the rest. Silvery iris, tinted brown or green, with 10 equally spaced spots. Spines stout; pungent only in juveniles. Preopercular angle 92°-103°. Strong scales cover the cheeks. Usually midline of thorax fully scaled, but pelvic ridges sometimes without scales.
Common in coral reefs; juveniles enter weedy estuaries (Ref. 4407). Juveniles and subadults form schools, adults in pairs. Adults feed on benthic seaweeds (Ref. 9813). Anterolateral glandular grooves with venom gland (Ref. 57406).
