Eastern Pacific: southern California to Peru. Misidentified as Epinephelus niveatus by some authors (Ref. 5995, 6852).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 48.0 cm SL male/unsexed; (Ref. 5222)
soft rays: 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).
Found on rocky reefs and soft bottoms (Ref. 89707). Reported to be often caught in shrimp trawls in central Gulf of California. Too rare to be of commercial interest.
