Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 4; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 65 - 71; Wirbelzahl: 47 - 52. Head width 11.7-13.6% SL; caudal peduncle depth 5.2-5.9% SL; anal fin rays 65-71; and vertebrae 47-52 (Ref. 52514).

Occurs most frequently in large slow-flowing rivers and lakes. Migrates into inundated forest during periods of high water, where it can be found around submerged woody vegetation. Feeds on fishes and crustaceans (Ref. 52514).

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): 3.7 ±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): Low vulnerability (12 of 100).
