Occurs in principal river beds, in upstream parts of rivers, downstream rapids, in backwater zones or on stony bottoms of pools with dead tree trunks. Active at dusk. Piscivorous. Emits loud grumblings (Ref. 35381). Secretes toxic mucus and the wounds caused by its pectoral spines are very painful. The female can preserve spermatozoids by coating them with original maternal secretions and inserting them in the epithelium of its genital tract (Ref. 27188). The presence of sperm in the mucus of the female's genital tract is indicative of internal fertilization (Ref. 35381).

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=0.01047 (0.00593 - 0.01849), b=3.10 (2.95 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.6 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).

Preiskategorie (Ref. 80766): Unknown.
