Key identification features
- Stout, heavy-bodied fish with smooth, scaleless skin ranging from black, brown, or olive to yellowish depending on species
- Broad, flattened head with a wide mouth and four pairs of sensory barbels ("whiskers") around the mouth and chin
- Tail fin is rounded to slightly squared, never deeply forked
- A single sharp spine at the leading edge of the dorsal fin and each pectoral fin
- A small, fleshy adipose fin between the dorsal and tail fins
Common look-alikes
- Channel catfish - has a deeply forked tail and scattered dark spots on a lighter body (spots fade with age), unlike the rounded tail of bullheads.
- Flathead catfish - noticeably flattened, wide head with a projecting lower jaw and mottled coloring, versus the more rounded head of bullheads.
Where you'll see one
Bullhead catfish (black, brown, and yellow bullhead) thrive in still or slow-moving water with soft, muddy or silty bottoms - ponds, small lakes, backwaters, and sluggish streams throughout much of North America. They tolerate low oxygen and warm, murky water better than most other catfish, often being the last fish species present in stressed habitats.
Frequently asked questions
How do I tell a bullhead from a channel catfish?
Look at the tail fin - bullheads have a rounded or squared tail, while channel catfish have a deeply forked tail.
Do bullhead species look different from each other?
Black, brown, and yellow bullhead are distinguished mainly by chin barbel color (dark for black/brown, pale or yellowish for yellow bullhead) and subtle body shading, though all share the same rounded tail and stout build.
