Morfologie | Morfometrie
Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 82; Anale zachte stralen: 62. Head short and oval-shaped dorsally; snout broadly rounded; eyes more laterally placed. Frontal fontanelle long and narrow; occipital fontanelle long and oval-shaped. Supraorbital and `dermosphenotic' bones separated, the latter somewhat reduced. Tooth plates broad. Pectoral spine straight; outer side with strong downward serrations. Gill rakers short and distantly set. Suprabranchial organ well developed. Openings of the secondary sensory canals display a regular pattern.
Facultative air-breathing (Ref. 126274); Nothing is known about the biology of this catfish (Ref. 78218).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00343 - 0.01757), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
