Tennessee Darter (Etheostoma tennesseense)

Description: 

As the common name suggests, the Tennessee Darter is found in the middle and upper Tennessee River Drainage in Tennessee, Mississippi, Alabama, Georgia, North Carolina, and Virginia. They live in rocky pools with bedrock substrate. Like many members of the Snubnose Darter group, Tennessee Darters have a bright red dot in the first membrane of their first dorsal fin, and their snouts are very blunt.
