Biology     Glossary (e.g. epibenthic)

Occurs in warm springs and their effluents, canals and weedy ditches, and stream pools (Ref. 5723). Food is mainly detritus (Ref. 36880). Some populations in caves (Ref. 27297).

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=0.01047 (0.00646 - 0.01697), b=3.11 (2.98 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
