Ozark cavefish

The Ozark cavefish is pinkish-white and reaches a maximum length of . The head is flattened, and it has a slightly protruding lower jaw. ==Habitat==

Caves which have populations of the Ozark cavefish all have a relatively large source of nutrients, such as bat guano or blown leaf litter. Ozark cavefish are able to tolerate the extremely low oxygen content of ground water found in caves. They tend to occur in flowing cave streams as opposed to quiet pools. The Ozark cavefish can receive nutrients from the tree roots above the cave. The roots are full of nutrients and water. The roots spread photosynthetic products in the cave, so organisms like Ozark cavefish and other species are able to feed on the roots. ==Distribution==

The geographic distribution of Ozark cavefish consists of northeastern Oklahoma, northwestern Arkansas, and southwestern Missouri. The fish is native to the Springfield Plateau of the Ozark Highlands. Currently, 15 caves in this area have verified populations. In Oklahoma, populations are known to occur in Delaware County. Historical records for Ottawa and Mayes Counties also indicate populations. Factors that have led to the decline of the Ozark cavefish include destruction of habitat, collecting of specimens, and disturbance by spelunkers. ==See also==
