What specific color defines the chin barbels, which aids in distinguishing *A. catus* from the Black Bullhead?
Answer
White
The color of the chin barbels, or whiskers, offers one of the clearest field marks for positively identifying the White Catfish. The defining characteristic referenced in its common name relates to these specific barbels being white in color, mirroring the pale coloration of the ventral side. This stark white coloration is crucial because it sets it apart from congeners like the Black Bullhead and Brown Bullhead, both of which possess dusky or black chin barbels. While the Yellow Bullhead also has white chin barbels, the tail structure (forked vs. straight) must be used concurrently to achieve absolute distinction between these two species.
