Perciformes facts for kids
Quick facts for kidsPerciformes
|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.
They are grouped as in the text Fishes of the World. The order is probably polyphyletic, and changes may occur in this and other teleost orders.
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.
