Ictiobus

Ictiobus, also known as buffalo fish or simply buffalo, is a genus of freshwater fish common in the United States, but also found in Canada, Mexico and Guatemala. They are the largest North American suckers, reaching up to 1.23 m (4.0 ft) in length. They are sometimes mistaken for carps because of the flat face and large, silver scales running along the body, though they lack the whisker-like mouth appendages common to carp. Buffalo fish live in most types of freshwater bodies where panfish are found, such as ponds, creeks, rivers, and lakes. Ictiobus was caught by the Lewis and Clark Expedition.
