What does the genus name *Ameiurus* translate to, referencing a feature of the yellow bullhead's tail fin?
Answer
Without notch
The scientific genus name *Ameiurus* directly relates to the morphology of the caudal, or tail, fin of these catfish. The term roughly translates to 'without notch,' which describes the appearance of the tail fin edge. Unlike some related species that may exhibit a slightly forked tail, the yellow bullhead typically presents a caudal fin edge that is generally rounded or straight, lacking a deep indentation or notch in the center. This structural feature is referenced within the species' formal classification, reinforcing its taxonomic description.
