Found in a wide range of habitats, sometimes in large schools well offshore and off bottom (Ref. 2850). Juveniles are pelagic (Ref. 36715). Adults feed on planktonic animals, mainly krill (Ref. 2850). Viviparous, with planktonic larvae (Ref. 36715). A very important prey species for predatory fishes and marine mammals (Ref. 2850). Not marketed due to its small size (Ref. 2850).
