Etymology: Amblyopsis: Greek, amblys = darkness + Greek, ops = shape (Ref. 45335).
Eponymy: Rosa Smith Eigenmann (1858–1947) was the wife of ichthyologist Carl H Eigenmann and an ichthyologist in her own right. [...] (Ref. 128868), visit book page.

Description synthétique
Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 7 - 8; Rayons mous anaux: 8. Pink-white. No eyes (vestigial eye tissues under skin). No pelvic fins. Usually 8 anal rays; 9-11 branched caudal rays.
Body shape (shape guide): elongated.
Adults inhabit subterranean waters of quite small cave streams. Preferred habitat in these caves is chert rubble though individuals are also found in areas of silt-sand substrates. Stomachs examined contained copepods which constituted about 70-90% by volume with the balance being primarily small salamanders, crayfish, isopods, amphipods and young of their own species (Ref. 34868). Eggs are carried in gill chambers of females (Ref. 205). Threatened by overfishing (Ref. 10172).
