Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 8 - 13; Espinas anales: 0; Radios blandos anales: 26 - 33; Vértebra: 82 - 91. Pectorals moderately long and narrow (Ref. 6885). Greenish brown above, silvery on sides and belly showing delicate iridescence (Ref. 6885). Branchiostegal rays: 8 (Ref. 35950).
Occur from near surface to bathypelagic depths. Feed mainly on small fishes but also takes small crustaceans and cephalopods (Ref. 6885). Predators include albacore, salmon, swordfish and lancetfish (Ref. 4525). Oviparous, with planktonic larvae (Ref. 35950).
