Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9 - 10; Anal soft rays: 8 - 9. Long flat head constricted behind snout. White. No eyes. No pelvic fins. No branched fin rays; incised fin membranes. Caudal fin with 4 rows of papillae; 21-22 caudal rays ( all unbranched).

Adults inhabit subterranean water (Ref. 5723). Highly cave-adapted species. Eggs are carried in gill chambers of females (Ref. 205). Threatened by groundwater pollution from agriculture runoff (Ref. 10172).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0088 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 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): Low vulnerability (10 of 100).
