Hardly differs from the European anchovy (E. encrasicolus) and can be identified from that description. For most of its range it is the only anchovy present, but in the extreme north it may overlap with species of Encrasicholina or Stolephorus, which have small needle-like scutes before the pelvic fins; species of Thryssa have compressed bodies and a keel of scutes along the belly.
Found mostly inshore: chiefly in bays, inlets and estuaries, sometimes in low salinities. Older individuals tend to move out to sea in winter and back in the spring. Forms compact schools much preyed upon by larger fishes, common dolphins and birds. Feeds on plankton. Spawns in inlets, bays and also estuaries, probably throughout the year but mainly in late spring to early autumn and especially about November to February. The eggs are ellipsoidal. Utilized as fish paste.
Spawns in inlets, bays and estuaries.
