marin; saumâtre pelagic-neritic. Tropical; 12°N - 21°S, 65°W - 34°W (Ref. 189)
Western Atlantic: Venezuela to Brazil.
Taille / Poids / Âge
Maturité: Lm ?  range ? - ? cm
Max length : 13.5 cm SL mâle / non sexé; (Ref. 37032); common length : 9.0 cm TL mâle / non sexé; (Ref. 5217)
Épines dorsales (Total) : 0; Épines anales: 0; Rayons mous anaux: 12 - 17. Body slightly compressed. Snout moderate, about 1/2 eye diameter; maxilla short, tip evenly rounded, failing to reach pre-operculum by 1/2 pupil diameter; pseudobranch short, about 3.4 eye diameter; gill cover canals of panamensis-type. Anal fin origin slightly behind base of last dorsal fin ray. Bright silver stripe along flank, about 3/4 eye diameter, dark bordered above.
Body shape (shape guide): elongated; Cross section: oval.
Occurs along the coastal zones and estuaries. Can tolerate a range of salinities, but there is no data on penetration into freshwater or fully marine habitats. More data needed (Ref. 12225).
