Western Atlantic: Bermuda and Massachusetts, USA to southern Brazil, including the southern Gulf of Mexico and the Caribbean. Adults are unknown from the northeastern coast of the USA.

Biology     Glossary (e.g. epibenthic)

A solitary species (Ref. 26340) inhabiting rocky and coral reefs (Ref. 9710). Adults feed primarily on fishes; juveniles mainly on crustaceans. Oviparous (Ref. 205). A protogynous hermaphrodite (Ref. 55367). Forms spawning aggregations (Ref. 55367). Common but difficult to approach (Ref. 9710). Marketed fresh and its flesh is of excellent quality.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01120 (0.00857 - 0.01463), b=3.06 (3.02 - 3.10), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.8 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.16; tmax=14; Fec=500,000).
Vulnerability (Ref. 59153):  High vulnerability (63 of 100) .
Price category (Ref. 80766):   Very high.
