Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Tropical and tropically influenced areas of the Atlantic Ocean. Western Atlantic: Canada (Ref. 5951) to Bermuda and at least North Carolina, USA (Ref. 5403) southward to northern Argentina (Ref. 3800). Eastern Atlantic: Madeira to northern Angola. Mediterranean (Ref. 50345). Reports from the Indo-Pacific are misidentifications.

Biology     Glossary (e.g. epibenthic)

Found on coral reefs and rocky bottoms (Ref. 3800). Forms small aggregations near the bottom (Ref. 10786). A nocturnal feeder (Ref. 5521), feeds mainly on small fishes, crustaceans and polychaetes (Ref. 3800). Most of its prey are larvae. Flesh considered excellent quality; marketed fresh (Ref. 5217).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01860 (0.01427 - 0.02424), b=2.92 (2.84 - 3.00), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.2 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (K=0.7).
Vulnerability (Ref. 59153):  Low vulnerability (25 of 100) .
Price category (Ref. 80766):   High.
