Các tia vây lưng cứng (tổng cộng) : 10; Các vây lưng mềm (tổng cộng) : 16 - 18; Tia cứng vây hậu môn: 3; Tia mềm vây hậu môn: 8. Distinguished by the following characteristics: generally pale reddish brown covered with numerous dark brown spots; 5 faint oblique dark bars on body; body depth less than head length, 2.6-3.0 times in SL; head length 2.3-2.5 times in SL; shallow notch above the angle of preopercle, serrae at angle slightly enlarged; slightly convex upper edge of operculum; subequal posterior and anterior nostrils; pelvic fins shorter than pectoral fins and their origin below or behind lower end of pectoral fin base; rounded caudal fin; ctenoid midlateral-body scales, with numerous auxiliary scales (Ref. 089707).
Abundant in patch reefs where it is readily caught by anglers. Inhabits depths of at least 50 m (Ref. 089707). Feeds mainly on crustaceans and fishes on rocky and sandy bottoms. During winter, it moves closer to the shore where it feeds heavily on swarms of pelagic red crab Pleuroncodes planipes.
