Description
Size: 34-52 cm.

Weight: 3-4 kg.

Color: Generally dark olive-brown to dark brownish gray with large pale blotches (most larger than the eye) and numerous small white spots overlying this pattern. Fins covered with small white spots, except for pectoral fins where the white spots are confined to the base.

Height 2.8-3, 3.4-3.6 in length with caudal. Head 2.2-2.5, 2.7-3 in length with caudal. Eye 4.5-5, as long as or a little shorter than snout. Interorbital space one half or three fourths of diameter of eye. Mouth oblique, maxillary reaching to below posterior half of eye, its width at its distal extremity 1.8-1.9 in diameter of eye. Praeoperculum rounded, rather coarsely serrated, the serrae at angle not enlarged. Middle opercular spine nearer to lower not farther back than upper, opercular flap obtuse, its upper border very convex. Teeth in rather borad bands, in two series on the sides of the mandibles, depressible teeth long, especially those near symphysis of upper jaw. Canines strong but short. Gillrakers rather short, 9 and 2 or 3 rudiments on lower part of anterior arch. Dorsal originating above base of pectorals. Third or third and fourth spine longest, as long as longest soft dorsal rays and one third of head. Last dorsal spine two third or three fourths of longest spine. Second anal spine much stronger and somewhat longer than third, almost as long as soft anal rays and as longest dorsal spine. Pectorals nearly as long as head without snout, ventrals slightly less than postorbital part of head, Caudal rounded. Scales mostly ciliated, those of head cycloid, maxillaries naked. Body robust. Serrae at the angle of the preopercle slightly enlarged, the upper edge of the operculum strongly convex. Posterior nostril of adults vertically elongate. Very similar to Epinephelus ongus which has longer pectoral fins, and a narrow white margin with broad blackish submarginal band on the median fins, which are absent or poorly developed in Epinephelus summana.

Fertilization external, oviparous.
