Percopsis transmontana
Percopsis transmontana, the sand roller, is a species of percopsiform fish endemic to the Columbia River drainage in the northwestern United States. This species grows to a length of 9.6 centimetres (3.8 in) TL. Sand rollers can live up to 6 years in slow-moving, sandy-bottomed streams and rivers among vegetation.
