The 68 species of suckers are found in freshwater rivers in North America, China, and northeastern Siberia. They can grow up to 1 meter long, but are usually less than 60 centimeters long. They have thick, fleshy lips that help them to attach themselves to rocks in the bottoms of fast-flowing rivers. They eat bottom-dwelling animals like worms, crustaceans, insects, and small fishes.
