Description
The riverweed darter is a small bottom-dwelling fish of the family Percidae (perches) occurring in flowing waters in the eastern United States. The species has an elongate, brown to greenish body with a mottling that provides camouflage, and reaches about 8 cm. Like other darters it lacks a swim bladder and rests on the bottom of rocky, fast-flowing riffles in creeks and small rivers, moving in short darts. The diet consists of small aquatic insect larvae. In the breeding season the males become more brightly coloured. The name refers to the riverweed (Podostemum) among which the fish lives.
