Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 11; Rayons mous dorsaux (Total): 16-17; Épines anales 3; Rayons mous anaux: 8. Maxilla without scales. Preopercle with rounded, only slightly enlarged, spines at its angle. Opercle with 3 flat spines, middle one the largest. 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).

Biologie     Glossaire (ex. epibenthic)

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).
