All Epinephelus — Dorsal fin with 10 or 11 spines and 13-19 rays. Anal fin with 3 spines and 8 or 9 rays (rarely 10). Most of upper edge of operculum free, not connected by skin to body. Caudal fin rounded, truncate, or emarginate. Head larger, its length contained 2.3-3.3 times in standard length. Middle opercle spine not reaching edge of operculum. Front nostrils variously shaped, but always closer to rear nostrils than to upper lip. A thin, moveable supramaxilla bone along upper, rear edge of maxilla (supramaxilla is covered by skin and not obvious, but it can be discerned by pushing the upper edge of the maxilla with a fingernail or dissecting needle; the supramaxilla is more apparent if the skin is cut and peeled off the free, rear part of the maxilla). Most teeth depressible (hinged). Scaly flap of skin joining upper part of inner (posterior) side of pectoral-fin base to body. Soft dorsal and anal fins mostly covered with thick skin and scales. Scales on body small, lateral scale series (69-146) more numerous than lateral-line scales. No large antrorse spine on corner of preopercle (but there may a few enlarged, ventrally-directed serrae there). Snout longer than eye diameter. Body depth usually not greater than head length, 2.5-3.6 times in standard length. Midlateral body scales rough.

Epinephelus striatus

Unique Characters: Dorsal-fin rays 16-18; anal-fin rays 8. Pelvic-fin origin below or behind lower end of pectoral-fin base; pelvic fins not longer than pectoral fins (usually less than 90% pectoral-fin length). Caudal fin convex or rounded. Second, third, or fourth dorsal-fin spines longest, longer than anterior dorsal rays. Body width usually less than half of body depth. No dark orange-brown or dark red spots.
