Etymology:

Issue
This species is placed in the genus EpinephelusBloch, 1793 in Eschmeyer (CofF ver. May 2011: Ref. 86870) as the placement of this species is uncertain in Craig et al. (2007: Ref. 83414).

Environment: milieu / climate zone / depth range / distribution range Écologie

marin récifal; non migrateur; profondeur 5 - 30 m (Ref. 5222). Tropical; 40°N - 24°N, 121°E - 142°E (Ref. 5222)

Distribution Pays | Zones FAO | Écosystèmes | Occurrences | Point map | Introductions | Faunafri

Northwest Pacific: known with certainty only from Japan, Korea, and China. Reports from other areas appear to be based on misidentifications of Epinephelus octofasciatus.

Épines dorsales (Total): 11; Rayons mous dorsaux (Total): 14-15; Épines anales 3; Rayons mous anaux: 9. Distinguished by the following characteristics: buff body with 7-8 dark bars; 3 pale interspaces below soft dorsal fin; last dark bar covers most of caudal peduncle and extends to the base of the last 2-3 dorsal fin rays; blackish brown pelvic fin rays; median fins blackish brown distally with narrow pale margin; dark maxillary streak usually hidden by maxilla; pale gill rakers and gill arches, without minute melanophores; depth of body contained 2.5-3.1 times in SL; head length 2.4-2.6 times in SL; distinctly convex interorbital area, convex dorsal head profile; diameter of posterior nostrils of adults 3-4 times bigger than anterior nostrils; angular preopercle, with enlarged serrae at angle; 1-2 small spines anterior to angle at lower edge of preopercle; serrate or smooth lower edge of subopercle and rear edge of interopercle, convex upper edge of operculum; maxilla reaches to below rear half of eye, distinct step on lower edge of maxilla; 2 rows of teeth on midlateral part of lower jaw (Ref. 89707).

Biologie     Glossaire (ex. epibenthic)

Occurs near shore, including semi-enclosed sea areas in rocky reefs in shallow waters (Ref. 11230). Feeds on fishes and crustaceans (Ref. 89707). Commercially cultured in Japan.
