Biology

provided by Fishbase
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).
