Short description Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 13; Mjukstrålar i ryggfenan (totalt) : 10; Taggstrålar i analfenan: 7; Mjukstrålar i analfenan: 9; Ryggkotor: 23. Upper body gray, green or brownish, silvery below; iris iridescent silver or golden. Body color patterns extend to the fins. Spines slender, pungent and venomous. Preopercular angle 88°-96°; cheeks scaled; midline of thorax, isthmus and midline of belly without scales. Frightened fish become mottled or with 6 diagonal zones across side. Tip of broad-based flap of anterior nostril reaching at least halfway to orifice of posterior nostril.
Inhabits shallow waters and generally in schools of 50 to several hundred individuals; prefers protected areas. Feeds by grazing on algae.

Estimates based on models
Preferred temperature (Ref. 123201): 24.7 - 29.2, mean 27.3 °C (based on 573 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00969 - 0.01425), b=2.99 (2.94 - 3.04), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trofisk nivå (Ref. 69278): 2.0 ±0.0 se; based on diet studies.
Generation time: 4.0 (1.3 - 4.9) years. Estimated as median ln(3)/K based on 11 growth studies.
Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (K=0.22, tm=1-2).
Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (31 of 100).
Nutrients (Ref. 124155): Calcium = 21.9 [10.0, 56.0] mg/100g; Iron = 0.57 [0.26, 1.33] mg/100g; Protein = 19.5 [18.5, 20.6] %; Omega3 = 0.21 [0.11, 0.45] g/100g; Selenium = 7.41 [2.58, 18.44] μg/100g; VitaminA = 52.3 [14.3, 193.5] μg/100g; Zinc = 1.38 [0.54, 3.02] mg/100g (wet weight); based on nutrient studies.
