Slackwater Darter (Etheostoma boschungi)

Description: 

This federally threatened species is found in five tributaries to the middle Tennessee River and the headwaters of tributaries of the Duck River system. As the common name suggests, Slackwater Darters live in slack water of small to medium streams during most of the year. In the breeding season, they move to groundwater seeps in pastures and forests to spawn. Slackwater Darters have an orange belly with an iridescent blue stripe along the side. Their scientific name honors Dr. Herb Boschung, a renowned ichthyologist at the University of Alabama.
