The Northern Sucker is a freshwater fish found primarily in the northern regions of North America. It typically inhabits rivers, lakes, and streams with a preference for slow-moving waters. This species is known for its elongated body and a distinctive sucker-like mouth, which it uses to feed on algae and detritus from the substrate. Northern Suckers can grow up to 24 inches in length and are usually brown or gray in color, helping them blend into their natural environment. They play an important role in their ecosystem by contributing to the nutrient cycle and serving as prey for larger fish and wildlife, such as bald eagles and otters.
