Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 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.

Trofisk nivå (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref.
