Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal soft rays: 13 - 14. Body elongated, without scales, almost covered with bony plaque, ventrally flattened in adults. Terminal mouth has three pairs of barbels. Lower jaw is shorter than the upper jaw. Eyes small (Ref. 35381).

Feeds on fruits when the forests are flooded and on the blades of macrophytes. Acts as seed dispersal agent (Ref. 6868). Reproduction occurs once a year and juveniles are often seen in large numbers in the estuary of the Amazon, in the region of Mario (Ref. 35381).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00813 (0.00358 - 0.01848), b=3.06 (2.86 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 2.0 ±0.00 se; Based on food items.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): High vulnerability (57 of 100) .

Price category (Ref. 80766): Unknown.
