Biología     Glosario (por ej. epibenthic)

Inhabits waters of low to moderate velocity, between 0 and 300 m elevation. Lives on creeks of more than 0.5 m deep, in ditches and near shorelines of large rivers. Generally swims in small groups at a depth of 20 cm. Insectivorous, the young eat mainly aquatic insects and the adults feed specifically on terrestrial insects (Ref. 36880). Found in a rapidly flowing rainforest stream (Ref. 26130).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Gestation lasts for about 24 days. Produces 10 to 30, rarely more, young. Reaches sexual maturity in about 5 or 6 months.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00451 - 0.01762), b=3.19 (3.02 - 3.36), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Nivel trófico (Ref. 69278):  3.4   ±0.45 se; based on food items.
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (tm=0.5).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
