The brown bullhead, Ameiurus nebulosus, is a fish of the Ictaluridae family that is widely distributed in North America. It is a species of bullhead catfish and is similar to the black bullhead (Ameiurus melas) and yellow bullhead (Ameiurus natalis). It was originally described as Pimelodus nebulosus by Charles Alexandre Lesueur in 1819, and is also referred to as Ictalurus nebulosus. The brown bullhead is also widely known as the “mud pout,” “horned pout,” “hornpout,” or simply “mud cat,” along with the other bullhead species. The brown bullhead is important as a clan symbol of the Ojibwe group of Native Americans. In their tradition, the bullhead or “wawaazisii” is one of six beings that came out of the sea to form the original clans.
