Descrição suscinta Chaves de identificação | Morfologia | Morfometria

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).

Ciclo de vida ou comportamento de acasalamento Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

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

Índice de diversidade filogenética (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).

Nível Trófico (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (tm=1).

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