Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Raggi dorsali molli (totale): 0; Raggi anali molli: 195 - 312. Body and head of living specimens uniformly black or very dark purple-brown with no humeral spot or patch; juveniles undergo striking pigmentation change from uniformly black by day to very pale with two distinct vertical saddle-like markings at night; dorsal margin of head well rounded (very convex) in adults (Ref. 52797).

Inhabits blackwater rivers and their seasonally inundated floodplain lakes and forests (Ref. 52797). Feeds on invertebrates (Ref. 52797).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.42 se; based on food items.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
