Könsmognad: Lm ?  range ? - ? cm
Max length : 13.5 cm SL hane/ej könsbestämd; (Ref. 37032); common length : 9.0 cm TL hane/ej könsbestämd; (Ref. 5217)
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 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).
