Pelagic species forming schools in coastal and oceanic waters, but also found near the bottom. Found singly, in small groups, or in schools (Ref. 12951). Feeds mainly on planktonic crustaceans, but also takes small schooling fishes (Ref. 12951). Ovoviviparous (Ref. 50449). Gestation period unknown (Ref. 114953).

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).
