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. Reported as Epinephelus compressus by Postel et al. (Ref. 6453).
印度-西太平洋: 索馬利亞與南非至日本,澳洲與紐西蘭。 除了日本,中國與韓國, 給 七帶石斑魚〔Epinephelus septemfasciatus〕 的大多數的分布記錄是可能以這種為依據。 被記錄為 Postel 等人的 黑帶石斑魚〔Epinephelus compressus〕 了。 (參考文獻 6453).

簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 11; 背的軟條 (總數) : 14 - 15; 臀棘: 3; 臀鰭軟條: 9. Distinguished by the following characteristics: body buff with 8 broad dark brown bars; blackish brown pelvic fins and distal half of the soft dorsal and anal fins; faint dark band from eye to the middle opercle spine; presence of blackish maxillary streak; minute melanophores covering gill rakers and gill arches; depth of body contained 2.2-2.7 times in SL; head length 2.4-2.5 times in SL; distinctly convex interorbital area, convex dorsal head profile; angular preopercle, enlarged serrae at angle; 0-3 small spines at lower edge of preopecle anterior to angle; distinctly serrate lower edge of subopercle and rear edge of interopercle; convex upper edge of operculum; posterior nostrils 2-3 times larger than anterior nostrils; maxilla reaches to below rear half of eye (Ref. 89707).

生物學特性     字彙 (例如 epibenthic)

Probably occurs in rocky reefs. Its apparent rarity may be due to its preference for relatively deep water.

可能出現在岩礁。 它的明顯稀有性可能由於它的對相當深的水的偏愛。
