خارهاي باله پشتي (کل): 0; شعاع نرم باله پشتي (کل): 15-18; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 10 - 13. Some variation in body depth and certain meristic characters; without pre- and post-pelvic scutes; W-shaped pelvic scute; pelvic fins less advanced. Distinguished from E. whiteheadi of southern African waters by having fewer anal fin rays and the pelvic fin base about 1/3 eye diameter. Isthmus with lateral flanges or shoulders (Ref. 188). Silvery with an olive green back. Scales deciduous (Ref. 7251). Also Ref. 3259.
Mainly inshore but has been occasionally taken 120 km from the Ecuador coast (Ref. 9291); also occur on shelf edge or surface (Ref. 11230), and between 50-150m (Ref. 028016). Usually occur in large schools (Ref. 2850). Epipelagic (Ref. 58302). Feed mainly on euphausiids and copepods (Ref. 9291). Oviparous, with planktonic eggs and larvae (Ref. 35601). Marketed fresh, salted and canned. Also processed into fishmeal (Ref. 9291).
