|Yellow perch (Perca flavescens)|
They have the widest range of sizes of any order of vertebrates, ranging from the 7 mm Schindleria brevipinguis to the 5 metre Makaira species. They first appeared and diversified in the Upper Cretaceous.
Some well-known members of this group are angelfish, barracuda, bass, blenny, cichlids, damselfish, filefish, goby, grouper, remora, swordfish, mackerel, pufferfish, tilefish, tuna, whiting, and of course perch.
Recent morphological and DNA sequence analysis has shown that several of the higher-level groupings of teleosts are evolutionary grades rather than clades. Examples of demonstrably paraphyletic groups include the Perciformes.
