How does the tail fin morphology of the Yellow Bullhead generally compare to that of a Channel Catfish?
Answer
It is generally not as deeply forked
When distinguishing between various North American catfish, the shape of the caudal fin, or tail fin, serves as a reliable characteristic. While sources note the Yellow Bullhead’s tail can appear slightly rounded or nearly straight, it decidedly lacks the deep fork characteristic of the Channel Catfish. This difference helps anglers confirm species identification in areas where both might be present. The presence of a deeply forked tail is a defining feature of species like the Channel Catfish, whereas the Yellow Bullhead exhibits a less pronounced incision.
