Short description Morfología | Morfometría

Dorsal fin reduced to a dorsal filament;

Prefers fast flowing rivers (Ref. 26543). Forms loosely associated groups in rocky habitats or river banks (Ref. 10605). Nocturnal (Ref. 26543). Each individual fish possesses a unique spatiotemporal pattern of electric organ discharge (EOD) potentials distributed over the body surface (Ref. 10595). Chirps and EOD frequency modulations are important elements of courtship behavior and are sensitive to testosterone levels (Ref. 10011, 10883). Seems to reach sexual maturity at 1 year of age, based on breeding experiments (Ref. 10011). Tuberous electro receptors are differentiated and functional in larvae at day 9; electric organ and electro receptors both present in the larvae at the time of first exogenous feeding (Ref. 10605).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Eggs of about 3 mm diameter are deposited in crevices. Several days up to 2-3 weeks between batch spawnings. Larvae hatch after 4 days and start feeding on day 11.

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=0.00355 (0.00145 - 0.00871), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.3 ±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 (tm=1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
