Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Spine anali: 0; Raggi anali molli: 12 - 14. Mouth small, pre-maxillae absent or minute and toothless; maxilla very short, just reaching to front border of eye, with two supra-maxillae; articulation of lower jaw under hind border of pupil or just behind. Dorsal fin origin well behind midpoint of body; anal fin origin under first quarter of dorsal fin base. In life translucent or even transparent.

Biologia     Glossario (es. epibenthic)

A riverine species collected some distance up a low-gradient swampy tributary of the Rio Negro (the Rio Jufari), Brazil and in the main river, in both cases the water generally darkly tinted, acid (pH 4-5) and low in dissolved ions. Feeds on dipteran larvae and pupae; also cladocerans. Males mature at 1.43-1.62 cm SL; females at 1.59-1.82 cm. Ovarian eggs are creamy or pale orange. A female of 1.73 cm had 20 eggs in the single ovary in January.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00253 - 0.01141), b=3.13 (2.96 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.35 se; based on food items.
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).
