Βιολογία     Γλωσσάρι (π.χ. epibenthic)

Found near rocky reefs in shallow water and in open water over deep banks (Ref. 2850). Adults live both off and on bottom (Ref. 2850). Juveniles are pelagic (Ref. 36715). Form schools (Ref. 2850). Feed on fishes (Ref. 27302). Viviparous, with planktonic larvae (Ref. 36715). Young are important prey species for other fishes, marine mammals and birds. Excellent food fish (Ref. 27436).
