Biology:Percomorpha
Percomorpha (from la perca 'perch', and grc μορφή (morphḗ) 'shape, appearance') is an extremely large and diverse clade of ray-finned fish. With more than 17,000 known species (including tuna, seahorses, gobies, cichlids, flatfish, wrasse, perches, anglerfish, and pufferfish) known from both marine and freshwater ecosystems, it is the most speciose clade of extant vertebrates.[1][2][3][4][5][6]
Evolution
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 c. 66 Ma ago.[7] The oldest known percomorph fossils are of the early tetraodontiforms Protriacanthus and Cretatriacanthidae from the Santonian to Campanian of Italy and Slovenia.[8] A higher diversity of early percomorphs is also known from the Campanian of Nardò, Italy, and these also show some level of diversification into modern orders, with representatives of the Syngnathiformes and Tetraodontiformes known.[9] Possibly the oldest percomorph is Plectocretacicus from the Cenomanian of Lebanon, which may be a stem-tetraodontiform; however, some morphological analyses indicate that it shows similarities with non-percomorph groups.[8][10]
Taxonomy
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.[6]
The Percomorpha are an extremely diverse group with at least 22 orders according to Eschmeyer's Catalog of Fishes.[11] Other authorities find a different number of orders depending on the classification used.
Numerous fossil percomorphs are known from the Late Cretaceous onwards, but most of these prior to the Eocene, and many afterwards, cannot be confidently assigned to extant percomorph lineages.[9] In the past they were placed within an expanded Perciformes, as with many extant groups, a treatment that is now known to be paraphyletic.[5]
