Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 125 m (Ref. 89707), usually 1 - 12 m (Ref. 90102). Tropical; 0°C - ; 16°N - 11°S, 75°E - 121°E (Ref. 5222)
Eastern Indian Ocean: southern India, Sri Lanka, and southern Indonesia. However, it is likely that its distribution is continuous from Pakistan to Indonesia. Record from the Chagos Archipelago is based on Epinephelus macrospilos (Ref. 6495).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 32.0 cm TL male/unsexed; (Ref. 5222)
soft rays: 8. Distinguished by having whitish or pale grey color; head, body and fins with numerous close-set round brown spots of unequal sizes; cycloid scales except region under pectoral fins; body with numerous auxiliary scales; greatest depth of body 3.0-3.5 in SL; rounded caudal fin; pelvic fins, 2.2-2.7 in head length (Ref. 90102); further characterized by flat or slightly concave interorbital area, convex dorsal head profile; rounded preopercle, with shallow indentation just above angle and slightly enlarged serrae at the angle; upper edge of operculum slightly convex; subequal posterior and anterior nostrils; maxilla reaches past vertical at rear edge of eye; 2 rows of teeth on midlateral part of lower jaw (Ref. 89707).
Occurs in shallow waters over coral reefs or rocky substrate. It appears to be a small species; a 17 cm SL fish from Sri Lanka has fairly well-developed ovaries. Solitary (Ref 90102).
