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]
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.
