簡単な記述
形態学 | 形態計測学
背面の脊椎 (合計): 0; 背鰭 (合計): 71-76; 臀鰭: 66 - 61. Devoid of pigment. Eyes extremely small; covered with skin; dorsally located. Head rectangular in dorsal outline; snout broadly rounded. Frontal fontanelle long and narrow; occipital fontanelle long and oval-shaped. Supraorbital and `dermosphenotic' bones fused. Premaxillary tooth plate rather broad. gill rakers long, slender and distantly set. Suprabranchial organ greatly reduced. Openings of the secondary sensory canals regularly arranged along flanks.
Facultative air-breathing (Ref. 126274); Lacks pigment. Lives in caves (Ref. 248) and is adapted to life underground (Ref. 78218); over shelves in open, clear water. Feeds on bat droppings, animal carcasses and terrestrial insects that fall into the lake (Ref. 7248).
