The classification of Perciformes remains a subject of ongoing scientific study because the relationships between the various groups within this order are not yet fully settled. While significant progress has been made, researchers continue to investigate the interrelationships between clusters of different perciform families.1
The current understanding of the order is complex, and it is likely not monophyletic. Consequently, scientists anticipate several changes to the classification, including:2
- The removal of certain groups from the order.1
- The addition of groups currently placed in other orders.1
- A substantial realignment of many groups within the Perciformes.1
These efforts are essential for refining our understanding of these bony fishes, which represent the largest group of fishes in the world.3
