Max length : 33.0 cm TL hane/ej könsbestämd; (Ref. 56557); common length : 25.0 cm TL hane/ej könsbestämd; (Ref. 56557)
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 15 - 18; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 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.
Body shape (shape guide): elongated; Cross section: circular.
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).
