Etymology: Mycteroperca: Greek, mykter, -eros = nose + Greek, perke = perch (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; depth range 5 - 30 m (Ref. 9342). Subtropical; 33°N - 23°N, 119°W - 106°W (Ref. 5222)
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 198 cm TL male/unsexed; (Ref. 2850); max. published weight: 91.0 kg (Ref. 5222)
Eastern Central Pacific: southern La Jolla, California, USA to Mazatlan, Mexico.
Found in rocky reefs and kelp beds. Juveniles are unknown in California waters and the few large adults that have been taken there are probably expatriates from a more southerly breeding population. Large adults feed on fishes (Ref. 9342). Reported to prey on juvenile hammerhead sharks. Its large size makes it an object of game fishing (Ref. 9342).
