Description
The Plains Sucker, scientifically known as Catostomus commersonii, is a widespread North American freshwater fish characterized by its elongated, cylindrical body and a distinctive subterminal, fleshy mouth adapted for bottom feeding. Its coloration typically ranges from olive-brown to tan with a lighter belly, often adorned with scattered dark spots. These hardy fish are crucial detritivores in their native ecosystems.
