Differs very little from the European anchovy (see E. encrasicolus) and can be identified from that description. Of other anchovies found in the southern part of its distribution, only species of Encrasicholina and Stolephorus are of similar appearance, but all have small spine-like pre-pelvic scutes (usually 2 to 7 scutes). Thryssa have compressed bodies and a keel of scutes along belly.
Occurs in large schools near the surface, mainly in coastal waters but as far out as over 1,000 km from the shore. Tends to move more northward and inshore in spring and summer. Juveniles associate with drifting seaweed (Ref. 12114, 12115). Feeds on copepods, but also on other small crustaceans, molluscan larvae, fish eggs and larvae and diatoms. Marketed fresh and salted, processed into fishmeal and oil (Ref. 12484).
