Body depth contained 2.7 to 3.3 times in standard length (for fish 13 to 31 cm standard length). Head length contained 2.25 to 2.6 times in standard length; interorbital area convex; dorsal head profile strongly convex; preopercle subangular, with 2 to 5 strong spines at the angle; upper edge of operculum straight, the uppermost spine rudimentary; maxilla reaches about to vertical at rear edge of eye; midlateral part of lower jaw with 2 rows of small, subequal teeth. Gill rakers 8 or 9 on upper limb, 16 to 18 on lower limb, total 22 to 26. Dorsal fin with XI spines and 15 or 16 rays, the third or fourth spine longest but shorter than the longest. ray, the interspinous membranes deeply incised; anal fin with III spines and 8 rays; pectoral-fin rays 17 to 19; pectoral fins longer than pelvic fins, pectoral-fin length contained 1.6 to 1.9 times in head length; caudal fin convex. Lateral-body scales distinctly ctenoid, with auxiliary scales in fish larger than 30 cm standard length; lateral-line scales 49 to 55; lateral-scale series 92 to 109. Pyloric caeca 12, in 3 bundles.
Colour: Head and body pale greyish brown dorsally, usually golden yellow ventrally; 4 broad dark bars on dorsal part of body, one on caudal peduncle and another often visible on nape; head and body with numerous small yellow spots; body and median fins also with small greyish white spots; soft dorsal, caudal, and sometimes the anal fin with prominent yellow margin paired fins dusky yellow.

Distribution

E. awoara occurs in the western North Pacific Ocean; it is known from Korea, Japan, Taiwan, China, Viet Nam, and islands in the South China Sea.

Ecology

This species is found in rocky areas as well as on sandy-mud bottoms. Juveniles are common in tidepools, and adults are caught in depths of 10 to 50 m. In captivity, E. awoara is an aggressive fish, spending much of its time chasing and biting other fishes, especially members of its own species.

Size

Maximum total length at least 60 cm.

Interchangeable taxa

The fish illustrated as “Epinephelus awoara” by Lindberg and Krasyukova (1971 :fig. 145) appears to be E. trimaculatus.
