Short description Morphology | Morphometrics

Dorsal spines (total): 12 - 14; Dorsal soft rays (total): 18-21; Anal spines: 3; Anal soft rays: 15 - 17. Body is white with a black bar running across the head through the eye. In juveniles, a second black bar runs from the base of the soft portion of the dorsal fin to the base of the anal fin. The dorsal, caudal and anal fins are either yellow or transparent (Ref. 4855). A narrow yellow bar from gill opening to pectoral base (Ref. 13442).

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

Western Atlantic: Florida, USA to Brazil. Larvae are sometimes swept northward which accounts for the sighting of juvenile specimens as far north as Massachusetts, USA during summer months. One record (one specimen, 3 cm) from Musquodoboit Harbor, Nova Scotia, Canada.

Biology     Glossary (e.g. epibenthic)

Inhabit shallow, coral reefs with clear water (Ref. 9626). Develop dusky bands at night. Generally common (Ref. 9710). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=-1.58000 (nan - nan), b=3.04 (2.89 - 3.19), based on LWR estimates for species & Genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.5 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (15 of 100) .
Price category (Ref. 80766):   Unknown.
