The vermilion darter is found only in Alabama in the Turkey Creek Watershed. It is critically endangered by development, both urban and industrial.

The runoff of sediment and toxic chemicals changes this habitat not only for fish, but for the aquatic insects they eat (and for humans I might add…polluted water is not good for humans either!). The populations have also been fragmented, which disrupts breeding.
