Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 15-16; Anal spines: 4; Anal soft rays: 9 - 10. Tip of membranes of spinous dorsal fin reddish or translucent, not whitish; posterior margin of upper jaw reaching posterior margin of pupil (Ref. 13608).

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

Western Atlantic: North Carolina, USA and Bermuda to Brazil, including the Gulf of Mexico and throughout the West Indies and Caribbean shores (Ref. 3724). Eastern Atlantic: Sao Tome Island and Gabon to Angola (Ref. 51178) and St. Paul's Rocks, St. Helena and Ascension Island (Ref. 6537).

Biology     Glossary (e.g. epibenthic)

Occurs in shallow coral reefs, as well as deeper offshore waters (Ref. 3724). A nocturnal species, hiding in deep crevices or under coral ledges during the day; at night it usually moves over sand and grass beds, taking mainly crabs and other small crustaceans (Ref. 3634). Capable of producing sounds (Ref. 6537). Marketed fresh (Ref. 3724).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.01220 - 0.01966), b=2.97 (2.90 - 3.04), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.3 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100) .
Price category (Ref. 80766):   Medium.
