Geographic Distribution of Species
Originally found in a deep well in Lebanon, Tennessee, the spring cavefish has a distribution within the central and south eastern United States. It inhabits select springs, spring runs/seeps, and caves from central and western Kentucky, west towards the Tennessee River, to south central Tennessee. It also is located in areas west across southern Illinois to southeastern Missouri.
The spring cavefish’s distribution has decreased from within its original streams and springs. This species is affected by the activities on the surface of the ground. Any activity that reduces water quality or quantity affects the spring cavefish. This species is vulnerable to pollution from many different sources. Some of these sources include nearby agricultural fields, pastures, septic tanks, sewage lagoons, urban runoff, mines, and livestock waste. Other issues with its distribution are some of the springs are intermittent. This means they fluctuate drastically in flow and turbidity, as a result of direct connections with surface drainage or they were enclosed as water supplies or otherwise modified by man.

There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
—Rutherford Birchard Hayes (1822–1893)
“Single-mindedness is all very well in cows or baboons; in an animal claiming to belong to the same species as Shakespeare it is simply disgraceful.”
—Aldous Huxley (1894–1963)
