Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 12 - 13; Espinas anales: 0; Radios blandos anales: 13 - 14; Vértebra: 46. Very long upper jaw, very long pectoral fin, and relatively short lower jaw. Head longer than lower jaw; pectoral fin about as long as head. Sixth anal ray of males widened but not elongated beyond the rest of anal fin rays. None of the male dorsal rays elongated beyond the rest of the dorsal fin.

Inhabits estuaries, lowland rivers and tributaries. A shoal-forming species which swims near the surface. Feeds on insects (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 2.9 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
