marinhas demersal; intervalo de profundidade 1 - 120 m (Ref. 36484), usually ? - 15 m (Ref. 3589). Tropical; 40°N - 24°S, 99°W - 9°E (Ref. 5222)
Western Atlantic: Massachusetts, USA and Bermuda to the Gulf of Mexico, the Caribbean and southern Brazil. Eastern Atlantic: Ascension and St. Helena islands; dubious records from the Canary Islands, Cape Verde and South Africa (Ref. 1496, 1953, 6572) are discussed by Heemstra (Ref. 6512). Also recorded from eastern Atlantic from Sao Tome in the Gulf of Guinea and from the Azores (Portugal) (Ref. 089707).
Length at first maturity / Tamanho / Peso / Idade
Maturity: Lm 30.4, range 25 - 36 cm
Max length : 65.0 cm TL macho/indeterminado; (Ref. 118680); common length : 35.0 cm TL macho/indeterminado; (Ref. 5217); peso máx. Publicado: 4.5 kg (Ref. 118249); Idade máx. registada: 25 anos (Ref. 118249)
Espinhos dorsais (total): 11; Raios dorsais moles (total): 16-17; Espinhos anais 3; Raios anais moles: 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).
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).
