Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; demersal; oceanodromous (Ref. 51243); depth range 55 - 525 m (Ref. 5222). Tropical; 43°N - 34°S, 98°W - 35°W

Western Atlantic: Massachusetts, USA to the Gulf of Mexico, Cuba, Trinidad, Rio de Janeiro and Sao Paulo (Ref. 47377), Brazil. Rare in the West Indies (Cuba, Haiti, and Trinidad). Reports from the eastern Pacific are apparently misidentifications of Epinephelus exsul.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 13 - 15; Anal spines: 3; Anal soft rays: 9. Distinguished by the following characteristics: dark reddish brown or brownish grey to almost black dorsally, dull reddish grey below; depth of body contained 2.4-2.6 times in SL; head length 2.1-2.5 times in SL; distinctly convex interorbital area; angular preopercle, rounded angle, with slightly enlarged serrae and with 1-2 small spines on lower edge just in front of angle; smooth interopercle and subopercle; subequal nostrils, posterior nostrils slightly larger; maxilla reaches well past eye; 4-5 rows of small teeth on midside part of lower jaw in adults and juveniles with 2-3 rows (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

A solitary species (Ref. 26340) usually found on rocky bottoms; juveniles are occasionally seen on jetties and shallow reefs (Ref. 89707). Adults feed on a variety of crabs, shrimps, lobsters, and fishes. Marketed fresh.

Estimates based on models

Preferred temperature (Ref. 123201): 13.8 - 23.1, mean 18.3 °C (based on 82 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.00685 - 0.02536), b=3.05 (2.89 - 3.21), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.61 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (K=0.05-0.14; tmax=24).
