Characteristic Dorsal fin with XI spines and 14 or 15 rays, the interspinous membranes deeply incised, the third or fourth spine longest, its length contained 2.5 to 2.9 times in head length and subequal to longest dorsal-fin rays; anal fin with III spines and 9 rays; pectoral-fin rays 18 or 19; pelvic fins subequal to or larger than pectoral fins, pectoral-fin length contained 1.8 to 2.0 times in head length; caudal-peduncle depth contained 0.9 to 1.3 times in its length; caudal fin rounded. Lateral-body scales ctenoid, with a few auxiliaries; lateral-line scales 65 to 71; lateral-scale series 114 to 126. Pyloric caeca very numerous, in 3 or 4 dendritic bundles with more than 80 terminal branches.
habitats Probably occurs in rocky reefs. Its apparent rarity may be due to its preference for relatively deep water. Maximum size: 130 cm TL. marine bathydemersal environment; depth range 40 - 350 m. 
Distribution Indo-West Pacific: Somalia and South Africa to Japan, Australia and New Zealand. Except for Japan, China, and Korea, most distribution records for Epinephelus septemfasciatus are probably based on this species. 
Utility The apparent rarity of E. octofasciatus may be due to its preference for relatively deep water.
