Korte beschrijving
Determinatiesleutels | Morfologie | Morfometrie
Dorsale stekels (totaal) : 0; Anale stekels: 0; Anale zachte stralen: 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.

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00234 - 0.01125), b=3.14 (2.97 - 3.31), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.

Fishing Vulnerability (Ref.
