Short description Morfología | Morfometría

Radios blandos dorsales (total): 7-10; Radios blandos anales: 7 - 10; Vértebra: 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).

Biología     Glosario (por ej. 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 Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

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).
Nivel trófico (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.
Resiliencia (Ref. 120179):  Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (K=0.43; tm=2; tmax=4).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100).
