Percina is a genus of small freshwater ray-finned fish, classified within the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches from North America. Along with similar fishes in certain other genera, members of Percina are commonly called "darters". More specifically, the genus as a whole is known as roughbelly darters, while certain species of Percina with a pattern of vertical bars on the flanks are called logperches.
The leopard 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 native to the United States, where it can be found only in the Little River drainage in Oklahoma and Arkansas. Its typical habitat is medium to large streams with rubble and boulder substrate. It feeds on small invertebrates on the riverbed and spawns mainly in March and April. It is threatened by impoundment, habitat loss and runoff from agricultural activities. It has never been a common species and has been listed as a threatened species in the United States since 1978, and the International Union for Conservation of Nature lists it as a "vulnerable species".

The longnose 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 United States.
The stargazing 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 United States.
Percina macrocephala, also known commonly as the longhead darter, is a species of freshwater ray-finned fish, a darter in the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes, and pikeperches. P. macrocephala is endemic to the United States.
The sickle darter is a recently identified 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 closely related to a well-known darter, Percina macrocephala. Discovered in 2007 in the upper Tennessee River drainage, the sickle darter is around 90.5 mm (3.56 in) in length and is a slender bodied, freshwater and benthopelagic fish that most likely feeds on small crayfish and mayflies, since it shares a large mouth and long snout with its sister species. The known distribution of the sickle darter is the upper drainage of the Tennessee River of Tennessee, North Carolina and Virginia. It is distinguished from all other Percina darters except its sister species P. macrocephala by a dark suborbital bar and a black bar subtending a medial black spot on the base of the caudal fin. It stays in mostly rocky, sandy, or silty substrates in clear creeks or small rivers in the Appalachian Mountains. The sickle darter spawns in late winter in gravel shoals. It also has large scales which make it different from macrocephala. It's known to be extirpated from most of its home habitat mainly because of agricultural practices that cause siltation and turbidity which causes most populations of the sickle darter to be widely scattered. But where it is found, it can be observed with regularity. Taking all this into consideration, the sickle darter does not have a formal conservation status under any federal or state law although its closely related species is considered a species of concern by the TWRA. Future management plans should include finding more locations of the sickle darter and decreasing further habitat destruction in known distributions by stating it as a fish of concern by state law.
