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=0.01202 (0.00976 - 0.01482), b=2.98 (2.93 - 3.03), 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.

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 (35 of 100).
