Pelvic fins shorter than pectorals and shorter than longest dorsal spine. Bases of soft dorsal and anal fins covered with scales and thick skin. 2 or 3 dark saddles along base of dorsal fin and another on top of caudal peduncle. Tan with red spots on head, body and fins, spots becoming larger ventrally (Ref. 26938); characterized further by: body depth less than head length, 2.6-3.2 times in SL; head length 2.1-2.5 in SL; interorbital area flat or slightly concave; preopercle evenly serrate; smooth subopercle and interopercle; subequal posterior and anterior nostrils (Ref. 089707).
颚骨没有鳞片。 前鳃盖骨有圆的, 只些微地增大了, 棘在其角上。 鳃盖有 3根平坦的棘，中央一最大的。 腹鳍短于胸鳍与短于长的背棘。 软背鳍与臀鳍的基底覆盖着鳞片与厚的皮肤了。 2 或 3 黑的鞍状斑沿着背鳍基底而且另一个在尾柄的顶端上。 黄褐色的在头部，身体与鳍上有红色的斑点, 斑点腹地变得比较大的.(参考文献 26938)
Inhabits rocky reefs. Usually solitary (Ref. 29). Difficult to approach (Ref. 9710). Juveniles often seen in rockpools (Ref. 86997). Feeds mainly on crabs (67%) and fishes (20%). In the Ascension I., feeds on juvenile Melichthys niger and young sea turtles. Its flesh is of good quality. Marketed fresh. Angling: Like other grouper, rock hind are caught by fishing at the right depth over an irregular bottom (Ref. 84357).
栖息于岩礁。 通常独居性的.(参考文献 29) 主要吃螃蟹 (67%) 与鱼 (20%) 。 在 Ascension 岛，它吃稚鱼 Melichthys niger 与幼鱼海龟。 困难的接近.(参考文献 9710) 它的肉是有好品质的。 在市场上销售生鲜地了。
