About Etheostoma duryi Henshall, 1889
Etheostoma duryi, commonly known as the black darter, is a species of darter that is endemic to the eastern United States. It is found in the Tennessee River drainage, within the states of Tennessee, Georgia, and Alabama. This species lives in rocky pools of streams and smaller rivers, as well as in the riffles adjacent to these pools. The black darter can grow to a maximum length of 7.2 cm (2.8 inches), though most individuals only reach around 5 cm (2.0 inches) in length. Its specific epithet duryi honors Charles Dury (1847–1931), who collected the original type specimens of the species.
