Individuals 3.5 cm may ascend rivers, presumably returning to the sea shortly after (Ref. 27547). Presumably young move offshore and reappear inshore as mature adults (Ref. 27547). At sea, they feed on small crustaceans, worms and jellyfish, as well as larval fishes (Ref. 6885, 10276). Females reach age 3, males age 2 (Ref. 27547). Oviparous, with demersal eggs and planktonic larvae (Ref. 35792). Eggs are laid on beaches with heavy surf action (Ref. 33312).
