Descrição breve
Chaves de identificação | Morfologia | Morfometria
Raios dorsais moles (total) : 7 - 10; Raios anais moles: 7 - 10; Vértebras: 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).
Body shape (shape guide): elongated.
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). They feed mainly on copepods, amphipods and isopods (Ref. 10294). Eggs are carried in gill chambers of females (Ref. 205).

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