Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 6 - 7; Anal spines: 2; Anal soft rays: 5. Differs from the known species, Protocobitis typhlops, by having the following characters: presence of light black pigmentation; body covered by rudimental scales except for head and abdomen; head length 24.1%-24.8% of SL; body depth 16.2%-16.3% of SL; inner rostral barbel length 19.8%-21.0% of head length; outer rostral barbel length 28.6%-30.2% of head length; maxillary barbel length 44.6%-46.0% of head length (Ref. 78524).

Collected from an underground water source (Ref. 78524).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00501 (0.00233 - 0.01079), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 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).
