Amblyopsis

The threatened Ozark cavefish, Amblyopsis rosae, is closely linked to the endangered gray bat.

Nowhere else do blind northern cave fish Amblyopsis spelaea (VU), Typhlichthus subterraneus and their spring cave-dwelling relative Chologaster agassizi co-exist.

Among the latter, the blind fish of the Mammoth Cave (_Amblyopsis spelacus_) is especially remarkable, because in this being the retrograde development of the organ of vision is accompanied by the production of certain ridges of skin on the body which are endowed with an extreme sensitiveness of touch, and which, according to a work lately published by Professor Von Leydig, are composed of little warts in which the nerve fibers end.

Far from feeling surprise that some of the cave-animals should be very anomalous, as Agassiz has remarked in regard to the blind fish, the Amblyopsis, and as is the case with blind Proteus with reference to the reptiles of Europe, I am only surprised that more wrecks of ancient life have not been preserved, owing to the less severe competition to which the scanty inhabitants of these dark abodes will have been exposed.

But these latter are not blind, and the argument only tends to show that the blind fish _Amblyopsis_ entered the caves before it was blind.
