Eastern Atlantic: Morocco to Angola, including the Mediterranean along the African coast. Range reported to extend south to Namibia (Ref. 27121).

Biology     Glossary (e.g. epibenthic)

Form schools. They occur frequently near the bottom, mostly in depths of 30 to 50 m. Also pelagic and found near the surface at times. Feed on small fish and invertebrates (Ref. 3195). Spawning grounds are located in shallow waters (Ref. 57055). Eggs are pelagic (Ref. 4233).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.01205 - 0.01901), b=2.94 (2.91 - 2.97), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.59 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.16-0.3; Fec = 480,000).
Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100) .
Price category (Ref. 80766):   Low.
