Sharphead Darter (Etheostoma acuticeps)

Description: 

The Sharphead Darter is restricted to the Nolichucky and Holston river systems in northeast Tennessee and southwest Virginia. As its name implies, this darter has an extremely pointed snout, like most other members of the subgenus Nothonotus. When this species was described in 1959, it was considered extinct because of the impoundment of South Holston Reservoir. It was later discovered in the Nolichucky River and rediscovered in the upper Holston River during surveys in 1967-1972. (Tile photo by Noel Burkhead)
