Scientific classification
Kingdom:	Animalia
Phylum:	Chordata
Class:	Actinopterygii
Order:	Perciformes
Family:	Percidae
Genus:	Etheostoma
Species:	E. simoterum
Binomial name

The common name of Etheostoma simoterum is the snubnose darter. It is one of the 324 fish species found in Tennessee.

Introduction

The following is a proposed conservation management plan for the snubnose darter Etheostoma simoterum. Two subspecies are recognized including the Cumberland snubnose darter Etheostoma simoterum atripinne and the Tennessee snubnose darter Etheostoma simoterum simoterum.<ref name="ref1"> The historical and current range of E. simoterum atripinne includes the Lower Tennessee River drainage unit and the Cumberland River drainage unit. The historical range of E. simoterum simoterum includes the Lower and Upper Tennessee River units, and it has been introduced into both the Licking Big Sandy Creek river unit and the Kanawha-New-Guyandotte-Little Kanawha River unit. Intergradation between the two subspecies occurs in the Lower Tennessee River unit. The mean standard length of Etheostoma simoterum is 45 mm, the reported clutch size is 152, and the maximum age is 1 year. The snubnose darter inhabits riffles and rock-bottomed pools in streams with low turbidity. As of 2000, Etheostoma simoterum was listed as currently stable, meaning that it is widespread and not in need of any immediate conservation action.
