Morphology | Morphometrics
Vertebrae: 43. Can be diagnosed by a combination of the following characters: rays on dorsal and ventral lobes of caudal fin with fused branches or not separated as in other species of Pseudoplatystoma; wide straight, dark vertical bars on sides; absence of loops on nape and associated areas; dorsal and ventral regions of pectoral fin pale with no spots; dorsal fin with few or no spots (sometimes 5 spots); 43 vertebrae; adipose fin with 6-7 large spots; areas surrounding the procurrent rays of dorsal fin without spots; posterior region of the metapterygoid wider than in other species, forming a depression or notch in the dorsal margin of the suspensorium (Ref. 59362).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00398 (0.00254 - 0.00625), b=3.15 (3.02 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 4.3 ±0.8 se; based on size and trophs of closest relatives
Generation time: 4.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (44 of 100).
