Biologia     Glossario (es. epibenthic)

Occur in sandy shores and bays, mostly in shallow surf zones, but also to 15 m depth. Often found near rocks and entrances to bays. Usually form small groups, but aggregate for spawning. Pelagic spawners (Ref. 56049). Feed on invertebrates, such as marine worms, clams, crabs and small crustaceans.

Estimates based on models

Preferred temperature (Ref. 123201): 15.9 - 19.5, mean 17.8 °C (based on 20 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00413 - 0.01752), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.44 se; based on food items.
Generation time: 3.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (tm=2.5; tmax=15).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100).
