توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل) : 0; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 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.

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.

جهندگی (Ref. 120179): زياد, كمينه زمان لازم براي دو برابر شدن جمعيت ، كمتر از 15 ماه (Preliminary K or Fecundity.).

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