Which Class classification groups the White Catfish with ray-finned fishes?
Answer
Actinopterygii
Biological classification places the White Catfish within a broad grouping defined by the structure of its fins. The Class Actinopterygii is the designation given to the ray-finned fishes, which represents the overwhelming majority of extant fish species. This classification is based on the skeletal support structure within their fins; the fins are supported by bony rays emanating from the base, rather than fleshy lobes. The White Catfish fits securely within this class, signifying its evolutionary placement among the bony fishes that utilize this specific type of fin structure for propulsion and maneuvering. This places it distinctively apart from lobe-finned fishes (Sarcopterygii) or cartilaginous fishes (Chondrichthyes).
