The Longnose Sucker is a freshwater fish found primarily in North America. It is known for its elongated snout, which helps it feed on the bottom of rivers and lakes. This species typically inhabits areas with gravel or sandy substrates, where it can find its preferred diet of algae and small invertebrates. Longnose Suckers can grow up to 30 inches in length and are recognized by their distinctive body shape and coloration, which often includes a mix of green and brown hues. They play an important role in their ecosystem by helping to maintain the health of aquatic environments, similar to other species in the Catostomidae family.
