Brown bullheads are ectothermic, heterothermic, and bilaterally symmetrical. [8] Brown bullheads can be distinguished from black and yellow bullheads by their yellow-black chin barbels, the absence of a hypopigmented bar at the base of the tail (which is present in black bullheads), and their 21–24 anal fin rays.

Ameiurus is a genus of catfishes in the family Ictaluridae.It contains the three common types of bullhead catfish found in waters of the United States, the black bullhead (Ameiurus melas), the brown bullhead (Ameiurus nebulosus), and the yellow bullhead (Ameiurus natalis), as well as other species, such as the white catfish (Ameiurus catus or Ictalurus catus), which are not typically called ...
Brown bullhead: Ameiurus nebulosus: Can be found in lakes and rivers. They will feed on fish, crayfish, and aquatic insects but will often scavenge on dead fish or other animals. Brown bullheads will typically grow to 8 to 16 inches long and weigh 1 to 2 pounds. They have been known to grow up to 20 inches in length and weigh about 4 pounds ...
The brown bullhead is also typically mottled brown and green on top instead of the darker black. Both the black and brown bullheads can easily be distinguished from the yellow bullhead by the color of the barbels on their chin: the yellow bullhead has white barbels under its mouth.
The Ictaluridae, sometimes called ictalurids, are a family of catfish native to North America, where they are an important food source and sometimes fished for sport.The family includes about 51 species, some commonly known as bullheads, madtoms, channel catfish, and blue catfish.
The pectoral spines have fine serrations, [7] but lack coarse teeth, which helps to distinguish snail bullheads from spotted bullheads (A. serracanthus). [10] A. brunneus can vary greatly in color but the most commonly observed morphs have brown to yellow-green backs with mottled sides and a white belly. [5]
Yellow bullheads are medium-sized bullheads that rarely grow larger than 2 lb (0.91 kg), but can reach up to 6.375 lb (2.892 kg). [8] Yellow bullheads may grow to a maximum total length (TL) of 60 centimetres (24 in), though they are more commonly 22.5 centimetres (8.9 in) TL, [9] and can live up to 12 years. [10]
Predation by introduced white bullheads contributed to the extirpation of Sacramento perch (Archoplites interruptus) from Thurston Lake by 1970. [4] The white bullhead commercial fishery in California was closed in 1953 due to concern of overfishing, [ 6 ] and it is not currently considered to be an invasive species by the state.
