What physical feature marks the Ictaluridae family, present on *A. nataloides*?
Answer
Adipose fin
The classification of the Yellow Bullhead within the family Ictaluridae, the North American Catfishes, is marked by several distinguishing anatomical traits common to the group. A key hallmark of this family is the presence of the adipose fin. This structure is a small, fleshy, rayless fin located on the back of the fish, positioned between the primary dorsal fin and the caudal (tail) fin. Its presence confirms the fish belongs to this specific family, setting it apart from certain other groups of fish.
