Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 17; Raggi dorsali molli (totale) : 9 - 11; Spine anali: 3; Raggi anali molli: 7 - 8. Distinguished from all its congeners by the combination of the following characters: lack of a dark infraorbital stripe or black preopercular markings; a caudal fin with distinct longitudinal bands; only 30 to 31 scales in E1 row; and small size, maximum TL approximately 16 cm (Ref. 57445).

Inhabits bare sandy bottoms in brooks and small rivers with remarkably strong current during the rainy season. Also occurs frequently in pools and ponds with more or less stagnant water during the dry season and the period of low water (Ref. 57445). A specimen measuring 6.5 cm SL has 80% plant matter (mainly seeds), aquatic insect larvae, detritus and sand grains in its stomach and adjacent intestine (Ref. 57445).

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=0.02042 (0.00898 - 0.04642), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.5 ±0.1 se; based on size and trophs of closest relatives

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).
