Short description Morphology | Morphometrics

This species is distinguished from its congeners by the following characters: body of breeding males with 15-18 dark irregular bars; absence of cephalic lateral line canals; body scales only under pectoral; D1 6; D2 7.5 branched rays; A 9.5 branched rays (Ref. 59043).

Biology     Glossary (e.g. epibenthic)

Occurs in clear karstic springs, lakes, slow-flowing streams and small rivers. Longevity is less than 2 years. Spawns after first winter with males defending the eggs in cavities under stones, plant material or shells. Juveniles are free swimming while adults are benthic. During summer droughts, this species may survive in underground waters (Ref.59043).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00412 - 0.01928), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
