Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Espinhos anais: 0; Raios anais : 28 - 34. Snout moderate, about 3/4 eye diameter; maxilla moderate, tip obliquely rounded, almost reaching to pre-operculum; gill cover canals of panamensis-type. Pectoral fins long, reaching to or just beyond pelvic fin base; anal fin very long, its origin under or just before or behind dorsal fin origin. A silver stripe along flank, about 3/4 eye diameter.
Occurs in shallow coastal waters (lagoons or estuaries), but apparently not in the sea. Inhabits somewhat murky brackish to salt water over mud or firm sand with a veneer of mud. One of the top three dominant fishes in the Huizache-Caimanero lagoon system in Mexico.
