Etymology: Mycteroperca: Greek, mykter, -eros = nose + Greek, perke = perch (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; depth range 2 - 137 m (Ref. 5222), usually 5 - 35 m (Ref. 40849). Subtropical; 33°N - 28°S, 92°W - 33°W (Ref. 5222)
Length at first maturity / Size / Weight / Age
Maturity: Lm 51.0  range ? - ? cm
Max length : 100.0 cm TL male/unsexed; (Ref. 26340); common length : 50.0 cm TL male/unsexed; (Ref. 5217); max. published weight: 18.5 kg (Ref. 40637)
Western Atlantic: Bermuda, Gulf of Mexico and the Caribbean south to Sao Paulo, Brazil.
Adults found on rocky and coral reefs, juveniles occur in shallow turtle grass beds. Also been taken in trawls over mud bottom in the northern Gulf of Mexico. Feeds mainly on fishes (mostly on coral reef species) and squids. Although often implicated in ciguatera poisonings, it is a desirable food fish; and even large (5 to 10 kg) fish from areas considered safe are sold in markets. Also caught with surface trolling. Sex-reversal has been observed (Ref. 5521).
