Short description Claves de identificación | Morfología | Morfometría

Radios blandos dorsales (total) : 9; Radios blandos anales: 16 - 19; Vértebra: 33 - 34. This species can be distinguished from its congeners by having an interrupted lateral line, besides a single perforated scale on caudal peduncle and a small dark spots on dorsal procurrent caudal-fin rays (Ref. 121599).

This species is often found near or at rapids with swift water currents and rocky bottoms. It can also be found in clear water, black water and relatively muddy rivers (Ref. 121599).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00428 - 0.02132), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 2.9 ±0.3 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

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