What is the typical range of anal fin rays possessed by Ameiurus catus?
Answer
22 to 25 rays
The White Catfish, *Ameiurus catus*, exhibits specific quantifiable physical characters that aid in its identification relative to other Ictalurids. Specifically, this species possesses a shorter anal fin base and typically counts between 22 to 25 rays in its anal fin. This ray count serves as one of the morphological cues used to differentiate it from species in the *Ictalurus* genus, which have evolved different anatomical configurations following speciation events.
