Short description

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).

Inhabits subterranean water (Ref. 5723). Found in caves which are near the water table and are therefore more uniform than other amblyopsid caves (Ref. 34868). Feeds mainly on copepods, amphipods and isopods (Ref. 10294).
