Ecologia
marino demersale; distribuzione batimetrica 50 - 130 m (Ref. 9342). Tropical; 33°N - 9°S, 118°W - 76°W (Ref. 5222)
Eastern Pacific: southern California to Peru. Misidentified as Epinephelus niveatus by some authors (Ref. 5995, 6852).
Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 48.0 cm SL maschio/sesso non determinato; (Ref. 5222)
Spine dorsali (totale) : 11; Raggi dorsali molli (totale) : 13 - 15; Spine anali: 3; Raggi anali molli: 9. Distinguished by the following characteristics: juveniles dark reddish brown with white spots in grid-like pattern of vertical series and horizontal rows on body and dorsal fin; caudal peduncle with visible dark saddle blotch; pale caudal and pectoral fins; dark brown anal and pelvic fins; black maxillary groove; adults dark brown lacking white spots; depth of body contained 2.3-2.7 times in SL; head length 2.2-2.5 times in SL; convex interorbital area; slightly produced angle of preopercle, with enlarged serrae; distinctly convex upper edge of operculum; vertically elongate posterior nostrils, 2-5 times larger than anterior nostrils; maxilla reaches to or beyond vertical at rear edge of eye; 2 rows of teeth on midlateral part of lower jaw (Ref. 89707).
