Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 25 - 29; Espinhos anais: 0; Raios anais moles: 16 - 19; Vértebras: 73 - 85. Scales small, more than 100 in lateral line. Gular plate narrow (Ref. 26938). Silvery overall, with bluish on upper surface (Ref. 7251). Branchiostegal rays: 26-33 (Ref. 4639).
Body shape (shape guide): elongated; Cross section: compressed.
Adults occur in shallow neritic areas, over muddy bottoms (Ref. 5217). Also found in brackish estuaries and juveniles are common in lagoons and hyper-saline bays (Ref. 5217). They form large schools close to the shore (Ref. 9987). Feed mainly on crustaceans and small fishes. Spawn in the open sea (Ref. 5217). Larval development is represented by profound changes in body form accompanied by 2 periods of length increase, interspaced by a period of length decrease (Ref. 4639). Noted for their habit of skipping along the surface of the water and for jumping after being hooked (Ref. 5521). Marketed fresh, salted and frozen but considered a second rate food fish (Ref. 3718). Rhynchobothrium bulbifer found in the viscera of the adult (Ref. 37032).
Spawns offshore, the larvae drifting towards the coast where they shelter and grow (Ref. 9987). Leptocephalus larvae are found in salinities as low as 0.0+ to 0.8 ppt (Ref. 75142).
