Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 11; Raggi dorsali molli (totale) : 16 - 18; Spine anali: 3; Raggi anali molli: 10 - 11. Distinguished by the following characteristics: greenish to greyish brown body color with small reddish brown spots and irregular pale spots and lines; fins with white margins; small portion of population exhibit xanthic pattern which is entirely bright yellow-orange, sometimes with few irregular black spots; depth of body contained 2.7-3.1 times in SL; head length 2.6-2.8 times in SL; angle of preopercle in adults with weakly-developed serrate lobe; posterior nostrils of large adults 2-3 times larger than anterior ones (Ref. 89707).
Prefers rocky areas in shallow water at depths of about 50 m. Adults feed on schools of the flatiron herring, Harengula thrissina, and anchoveta, Cetengraulis mysticetus when available; if not, on other schooling fishes or non-schooling fishes. Most feed at dawn and dusk, with a peak in activity about 20 minutes after sunset. Juveniles feed throughout the day on a variety of benthic fishes and crustaceans.

Estimates based on models
Preferred temperature (Ref.
123201): 20.6 - 26.8, mean 22.4 °C (based on 24 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00429 - 0.02028), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.5 ±0.80 se; based on food items.
Generation time: 11.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (K=0.09).
Fishing Vulnerability (Ref.
