Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 7 - 10; Anal soft rays: 7 - 10; Vertebrae: 28 - 29. Pink-white. No eyes (vestigial eye tissues under skin). Large, broad head. Caudal fin with 0-2 rows of papillae (Ref. 5723) and a vertical basal row (Ref. 10294); 10-15 branched caudal rays (Ref. 5723).

Biology     Glossary (e.g. epibenthic)

Adults inhabit subterranean water (Ref. 5723). Found in caves which are near the water table and are therefore more uniform than other amblyopsid caves (Ref. 34868). Feed mainly on copepods, amphipods and isopods (Ref. 10294). Eggs are carried in gill chambers of females (Ref. 205).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Incubates eggs in gill chamber of females (Ref. 205). Fecundity is very low, perhaps fewer that 50 ova per female (Ref. 10294).

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   ±0.37 se; based on food items.
Generation time: 2.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.43; tm=2; tmax=4).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100).
