Morphology | Morphometrics
soft rays: 8. Absence of eyes and pigmentation; presence of a nuchal cavity; slightly compressed body, tapering posteriorly; head depressed, conical when seen from above (Ref. 37842).
Cave-restricted species. Inhabits headwater stream with a relatively low volume of water flowing over rocks, alternating with small pools and gravel-bottomed shallow reaches (Ref. 42927). Few individuals were seen adhering to rocks in fast-flowing, well-aerated water or swimming in the pools (Ref. 42927). Exhibits agonistic behavior upon encounter (Ref. 42927). Feeds on benthic microorganisms (Ref. 58784).

Bayesian length-weight: a=0.00708 (0.00339 - 0.01477), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.7 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
