Description

The bigmouth buffalo is a large sucker (Catostomidae) from North America, in the Mississippi basin, the Great Lakes and the Hudson Bay drainage. The species can reach about 123 cm and has a stocky, bronze-brown body and, unlike most suckers, a large, obliquely set terminal mouth. It inhabits main channels, pools and backwaters of rivers, lakes and reservoirs in water less than five metres deep. It filters zooplankton such as water fleas and copepods, supplemented with midge larvae. The species is remarkable: it is among the longest-lived freshwater fishes in the world and can reach well over a hundred years of age.
