What key feature defines the Class Actinopterygii classification for *A. ocellatus*?
Answer
Ray-finned fishes
The classification of the Pacific wolf eel into the Class Actinopterygii signifies that it belongs to the ray-finned fishes. This class represents the vast majority of extant fish species today. The internal structure supporting the fins in these fishes is fundamentally different from that of lobe-finned fishes. The presence of ray-like supports within the fins reflects the standard bony fish blueprint inherited by *A. ocellatus*, which allowed it to evolve an elongated shape through convergent evolution rather than adopting the specialized skeletal architecture found in true eels.
