Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 11.3 cm TL maschio/sesso non determinato; (Ref. 80009); common length : 6.0 cm TL maschio/sesso non determinato; (Ref. 5217)
Spine dorsali (totale) : 0; Spine anali: 0; Raggi anali molli: 14 - 18. Body fairly slender, moderately compressed. Snout short, a little over 1/2 eye diameter; maxilla moderate, tip bluntly rounded, failing to reach pre-operculum by 1/3 to 1/2 pupil diameter; gill cover canals of walkeri-type. Anal fin short, its origin a little behind base of last dorsal fin ray. A silver stripe along flank, widening to about 1/2 eye diameter over anal fin base (Ref. 189).
Body shape (shape guide): elongated; Cross section: oval.
Occurs in estuaries and rivers, apparently tolerating only very low salinities. Breeds in December: a female of 5.8 cm SL having 2,000 eggs was caught from the Orinoco River mouth (Ref. 12225)..
