Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 2 - 3; Raggi anali molli: 49 - 53; Vertebre: 44 - 45. Distinguished from all other species of Kryptopterus by the following unique combination of characters: body with pale brown coloration with scattered black spots on flanks; head width 11.4-12.0% SL; body depth at anus 22.3-24.3% SL; eye diameter 20.3-25.3% HL; maxillary barbels extending to anal origin; anal fin with 49-53 rays; and gill rakers 16-17 (Ref. 52489).

The type locality is a small river under primary forest cover and with a moderate current, turbid water and with many fallen trees and a muddy substrate. Also found in areas with clear water and substrate consisting of sand and gravel (Ref. 52489).

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=0.00562 (0.00279 - 0.01132), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
