The bigmouth buffalo, the largest member of the sucker family, lives in lakes and rivers in most of Minnesota except for the Lake Superior watershed. Unlike many fish, it can survive in cloudy, warm water. Unlike other members of the sucker family, the bigmouth buffalo has a mouth at the front of its face. It looks like a carp without barbels. They can grow 3 feet long or longer and weigh more than 50 pounds. Bigmouth buffalo range in color from green to gold to almost black. They have a coppery sheen.
