The Roanoke hogsucker is a robust sucker with dark saddles on its body. It has a large square head with protruding lips. They grow to about three to six inches in length. The Roanoke hogsucker can be distinguished from the Northern hogsucker by the light horizontal lines on its sides and back.
Endemic to the Dan River subbasin in Virginia and North Carolina, which is part of the larger Roanoke River basin.
The Roanoke hogsucker prefers fast-flowing, high-gradient streams with a mix of rocky substrates including some sand, often with overhanging ledges or banks.
Males mature between one and two years, females between two and three. Females live longer (four to five years to males’ three to four) and spawn in the spring. These cryptic fish depend on good water quality to survive, as they feed on a diversity of aquatic insects and some leafy detritus. Details of this fish’s life history are not yet known.
