Maturity: Lm 16.4  range ? - ? cm
Max length : 33.0 cm TL male/unsexed; (Ref. 56557); common length : 25.0 cm TL male/unsexed; (Ref. 56557)
soft rays: 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.
Restricted to the northwestern Atlantic: from the Bay of Fundy to the Gulf of Mexico.
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).
