Percomorpha (from Latin perca 'perch', and Ancient Greek μορφή (morphḗ) 'shape, appearance') is a large clade of ray-finned fish that includes the tuna, seahorses, gobies, cichlids, flatfish, wrasse, perches, anglerfish, and pufferfish.[1][2][3][4][5]
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. 65 Ma ago.[6]
The two cladograms below are based on Betancur-R et al., 2017.[4] Percomorphs are a clade of teleost fishes. The first cladogram shows the interrelationships of percomorphs with other living groups of teleosts.
