背棘 (总数) : 13; 背的软条 (总数) : 10; 臀棘: 7; 臀鳍软条: 9; 脊椎骨: 13. Indian Ocean subspecies. 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.

生物学特性     字汇 (例如 epibenthic)

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).

常见于珊瑚礁; 稚鱼进入杂草丛生的河口。 (参考文献 4407) 稚鱼与亚成鱼形成鱼群, 成对的成鱼。 成鱼吃水底的海草。 (参考文献 9813) 用毒液腺的前外侧的腺凹槽.(参考文献 57406)
