Biología     Glosario (por ej. epibenthic)

Facultative air-breathing (Ref. 126274); Occurs in streams and lakes (Ref. 44091) and in weedy, mud-bottomed canals (Ref. 5723). Benthic (Ref. 58302). Nocturnal, feeds on algae (Ref. 13371), but will also feed on worms, insect larvae, and other bottom-dwelling aquatic animals (Ref. 44091). Spawning period peaks once a year (Ref. 56986). Reproductive behavior includes digging of burrows for egg laying (Ref. 82067). May exhibit male parental care (Ref. 56986).

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=0.02399 (0.01241 - 0.04636), b=2.90 (2.74 - 3.06), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  2.2   ±0.12 se; based on food items.
Resiliencia (Ref. 120179):  Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (tm=1; Fec = 1,983).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (40 of 100).
