Percomorpha

Percomorpha are the most diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoic era. Fossil evidence shows that there was a major increase in size and abundance of teleosts immediately after the mass extinction event at the Cretaceous-Paleogene boundary {{Circa|66 Ma}} ago.{{cite journal|last1=Sibert|first1=E.

Many of the orders placed in Percomorpha today were originally placed in an expanded Perciformes, hence many sources often referring to that order as the most diverse vertebrate clade. However, more recent studies have found such a placement to be paraphyletic, and many have thus been moved to their orders within Percomorpha.

The Percomorpha are an extremely diverse group with at least 22 orders according to Eschmeyer's Catalog of Fishes.{{Cite web |last=Fricke |first=R. |last2=Eschmeyer |first2=W.
