Bigmouth buffalo

It is commonly called the gourdhead, marblehead, redmouth buffalo, buffalofish, bernard buffalo, roundhead, or brown buffalo. The bigmouth buffalo is not a carp, nor is any other fish in the sucker family. Although they share the same order, each belong to different suborders and are native to separate continents. The bigmouth buffalo is typically a brownish olive color with dusky fins, but can vary greatly in color across individuals. Like other catostomids it has a long dorsal fin, but unlike all others it has a terminal (forward-facing) mouth reflecting its unique, pelagic feeding ecology. It is the largest of the buffalo fish and can reach a length of more than 4 ft (1.2 m) and 65 lb (29 kg) in weight. Generally, it lives in sluggish areas of large rivers and in lakes. Bigmouth buffalo populations have been in decline in the northern extent of their range since the 1970s, including parts of Minnesota, North Dakota, and Canada
