Ecologia
marino; salmastro; non migratori; distribuzione batimetrica 0 - 32 m (Ref. 96339). Subtropical; 32°N - 4°S, 115°W - 78°W (Ref. 54323)
Eastern Pacific: southwestern coast of Baja California, Mexico and from the Gulf of California to northern Peru (up to the Bay of Sechura). Apparently reaching Los Angeles, USA, but these are perhaps releases from tuna boats.

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Spine anali: 0; Raggi anali molli: 17 - 24. Head large and deep. Snout short and pointed, about 2/3 eye diameter; maxilla moderate, tip blunt, just failing to reach lower jaw articulation; lower gill rakers fine and numerous, increasing in large fishes; no gill rakers on posterior face of third epibranchial. Branchiostegal rays 8, long and slender; branchiostegal membrane broad. Silver stripe disappearing at about 8-10 cm SL.
Occurs inshore, principally over mud flats and forming quite large schools. Apparently not making long migrations along sandy or rocky areas. Juveniles feed principally on diatoms, also silico-flagellates, dinoflagellates and small crustaceans; adults also mainly on benthic diatoms. Used as tuna baitfish. Processed into fishmeal and oil.
