Max length : 24.0 cm TL macho / no sexado; (Ref. 5217); common length : 20.0 cm TL macho / no sexado; (Ref. 5217); peso máximo publicado: 66.30 g (Ref. 118626)
Espinas dorsales (total) : 0; Espinas anales: 0; Radios blandos anales: 31 - 37. Snout about 3/4 eye diameter; maxilla long, tip pointed, reaching to or a little beyond edge of gill cover; anterior gill rakers mere stumps; hind border of gill cover with a small triangular projection; panamensis-type gill cover canals. Pectoral fin long; anal fin origin below midpoint of dorsal fin base. A silver stripe along flank in small individuals, disappearing with age (Ref. 189).
Body shape (shape guide): elongated; Cross section: oval.
A coastal species that apparently forms large schools. Enters brackish and fresh waters. Feeds on small fishes (including clupeoids) and prawns (Ref. 12225). Seems to spawn over an extended period in Costa Rica (small fishes caught in February, September and October). Marketed fresh (Ref. 9298).
Life cycle and mating behavior
