Eastern Atlantic: Oslo, Norway south to Dakar, Senegal but the range is centered in the southern Mediterranean Sea. Not known from Madeira, the Canary Islands or Cape Verde.

Biology     Glossary (e.g. epibenthic)

Adults are neritic, confined primarily to temperate waters, but juveniles may be encountered in waters of up to 30°C. Form small schools at the surface so that the first dorsal fin stands out of the water like that of sharks, also frequently associated with birds. Feed on small fishes, especially sardines, anchovies, jacks, mackerel, bogue and others. Eggs and larvae are pelagic (Ref. 6769). Marketed canned or frozen.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

A female weighing 5 or 6 kg may carry some 500 to 600,000 eggs which are spawned in portions.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00416 - 0.02000), b=3.04 (2.86 - 3.22), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.80 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm<=4).
Vulnerability (Ref. 59153):  Very high vulnerability (76 of 100) .
Price category (Ref. 80766):   Medium.
