Swannanoa darter

Species of fish

The Swannanoa darter is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to the eastern United States where it occurs in the drainage of the Tennessee River. It prefers flowing water in riffles in cool, clear mountain streams, with boulder substrates. The diet and natural history of this species have been little studied but are probably similar to those of its close relative, the greenside darter. The population trend of this fish seems to be stable and it is a common species with numerous sub-populations over its limited range, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
