This species is distinguished by the following characters: front of eye without the elongate groove; enlarged scales above the pectoral-fin base and just behind the gill opening to form a flexible tympanum; the scales of the caudal peduncle with 2 longitudinal rows of large anterior-projecting spines; the slightly rounded caudal fin with compressed peduncle; head and body colour green to brown with diagonally curved orange lines and a large round black blotch covering most of the caudal-fin base; rays of soft dorsal, anal and pectoral fins orange and also the caudal fin (Ref. 10920, 9770).
Adults which are territorial in nature occur in coral-rich areas of deep lagoon and seaward reefs from the lower surge zone to at least 50 meters (Ref. 48637). They feed on a variety of benthic organisms such as algae, echinoderms, fishes, mollusks, tunicates, sponges, and hydrozoans. Eggs are laid as one cluster in a shallow excavation on sand or rubble along channels. (Ref. 1602). Marketed fresh and dried-salted (Ref. 9770).
Spawning behaviour may involve loose aggregations and nesting occurs in channels. The eggs are laid in a single spongy cluster in a shallow excavation in rubble or sand. Hatching occurs at night (Ref. 37816). Nests are guarded by one or at times two adults (Ref. 9778).
