Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 12.4 cm SL male/unsexed; (Ref. 57607)

Short description Morphology | Morphometrics

Dorsal soft rays (total): 7-10; Anal soft rays: 5 - 8; Vertebrae: 37 - 38. Differs from all its congeners by the following combination of characters: body completely scaled with well developed eyes; lateral line curved possessing 57-64 scales; pectoral fin not reaching the origin of the pelvic fin and the last unbranched ray of the dorsal fin clearly serrated along its posterior edge; 8-9 predorsal vertebrae; 8-9 gill rakers; joints of dentary-angulars not close to each other at the isthmus; and a slightly inferior mouth with the upper jaw (6.2-7.4% SL) protruding slightly beyond the lower one (5.7-6.7% SL) (Ref. 57607).

Biology     Glossary (e.g. epibenthic)

Inhabits subterranean river with water surface about 10-20 m inside the mouth of a small cave located about 50-100 m up from the bottom of a 4 square km lowland depression in a mountainous region (Ref. 57607). The subterranean water flows out during the flood season, making the lowland depression looks like a small lake (Ref. 57607).

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=0.01175 (0.00548 - 0.02519), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
