Suckers are a type of fish belonging to the family Catostomidae. They are commonly found in North America and are known for their elongated bodies and large mouths. Suckers typically inhabit freshwater rivers and lakes, where they feed on algae, detritus, and small invertebrates. These fish are often recognized by their distinctive sucker-like mouths, which they use to graze on the bottom of water bodies. Some popular species include the White Sucker and the Northern Sucker. Suckers play an important role in their ecosystems by helping to maintain the health of aquatic environments.
