Percomorpha

Clade of ray-finned fishes


Percomorpha (from Latin perca 'perch', and Ancient Greek μορφή (morphḗ) 'shape, appearance') is a large clade of ray-finned fish with more than 17 000 known species that includes the tuna, seahorses, gobies, cichlids, flatfish, wrasse, perches, anglerfish, and pufferfish.[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 ca. 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]

Evolution of ray-finned fishes, Actinopterygii, from the Devonian to the present as a spindle diagram. The width of the spindles are proportional to the number of families as a rough estimate of diversity. The diagram is based on Benton, M. J. (2005) Vertebrate Palaeontology, Blackwell, 3rd edition, Fig 7.13 on page 185.
