FBname: Northern cavefish
Comments: Blind and depigmented.  Despite the lack of eyes it does respond to light and moves away from it (scotophilia).  Inhabits subterranean water or caves which have consolidated mud-rock substrates in shoals and silt-sand substrates in pools but is more often found in caves with uniform silt-sand substrates (Ref. 34868).  Has low reproduction rate and broods eggs in gill cavity for up to 4-5 months (Ref. 557; 34868; 27795).  Can live for 2 years without food because of low metabolic rate (Ref. 5326).  Top predator.
