Bullheads belong to the catfish family. They have no scales and on their face they have sets of wormlike feelers, called barbels. Of Minnesota's three bullhead species--black, brown, and yellow--the black bullhead can live in the most polluted waters.
Bullheads are small, cold-water relatives of scorpionfish and the stonefish. Like them, they are stout, bottom-living fish with a broad head, large mouth, and spiny fins. The long-spined bullhead also has a long, sharp spine on each cheek.
Bullheads spawn in the late spring when water temperatures approach 21øC. One or both parents excavate a shallow nest in a protected area of mud or sandy bottom. Spawning occurs in the daytime.
