Occurs mainly in the open sea, occasionally approaching the shore and sometimes forming large schools.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00239 - 0.01051), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.00 se; based on food items.
Generation time: 3.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Fec=9,986-53,430).
Fishing Vulnerability (Ref.
