    • n blindfish A cave-fish, one of the Amblyopsidæ, having eyes rudimentary and useless for vision. The best-known is the Amblyopsis spelæus, or blind-fish of the Mammoth Cave of Kentucky; another is Typhlichthys subterraneus. Amblyopsis spelæus attains occasionally a length of 3 to 5 inches; it has rudimentary and functionless eyes, and ventral fins small and of 4 rays each. The color is pale as if bleached. It inhabits the subterranean streams of Kentucky and Indiana, especially those in the Mammoth Cave. Typhlichthys subterraneus is a much smaller species and destitute of ventral fins. It is an occasional associate of the Amblyopsis. See cut under Amblyopsis.
