Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 10; Spine anali: 7; Raggi anali molli: 9; Vertebre: 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.

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).

Trophic level (Ref. 69278): 2.0 ±0.0 se; based on diet studies.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (K=0.22, tm=1-2).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (35 of 100).

Price category (Ref. 80766): High.
