''Etheostoma obama'', the spangled darter, is a species of darter endemic to the eastern United States where it is only known to occur in the Duck River and the Buffalo River, both in Tennessee.〔 ==Discovery and naming== Layman, of Geosyntec Consultants, and Rick Mayden, Department of Biology at Saint Louis University, studied the freshwater darters, most of which are native to the U. S. states of Alabama and Tennessee. While they were studying color variation of ''Etheostoma stigmaeum'', the speckled darter, Layman and Mayden discovered that there were populations with enough variation that they should be described as unique species.〔 This species is one of five distinct species were named after former U.S. presidents and a vice-president, based on their leadership in conservation. ''E. obama'' was named after Barack Obama, for his work "particularly in the areas of clean energy and environmental protection, and because he is one of our first leaders to approach conservation and environmental protection from a more global vision," according to one of the scientists, Steve Layman, who named the new species.
