Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 10; Anal spines: 7; Anal soft rays: 9; Vertebrae: 13. Color the same as in S. vulpinus except for the blackish spot posteriorly on the upper side of the body. Caudal peduncle only slightly incised. Spines stout, pungent, and venomous. Preopercular angle 109°-119°. Variable cheek squamation; usually covered with scales, 7-10 rows deep below center of orbit, occasionally a few scattered scales present below eye; a triangular area from lower edge of orbit to angle of mouth always fully scaled. Fully scaled midline of thorax.

Biology     Glossary (e.g. epibenthic)

Inhabits rich coral areas of lagoons and outer reefs, often among staghorn corals (Ref. 90102). Small juveniles occur in schools of up to a few hundred fish, larger juveniles and adults occur in pairs. Feeds on seaweeds (Ref. 9813).

Estimates based on models

Preferred temperature (Ref. 123201): 25.4 - 29.1, mean 28.2 °C (based on 1226 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00650 - 0.03213), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.30 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (14 of 100).
Price category (Ref. 80766):   High.
Nutrients (Ref. 124155):  Calcium = 50.7 [24.5, 121.4] mg/100g; Iron = 0.752 [0.362, 1.794] mg/100g; Protein = 18.7 [17.1, 20.2] %; Omega3 = 0.119 [0.062, 0.237] g/100g; Selenium = 20.4 [8.0, 50.3] μg/100g; VitaminA = 40.9 [11.5, 141.9] μg/100g; Zinc = 1.4 [0.6, 3.0] mg/100g (wet weight);
