# Carangiformes

Carangiformes is a large, diverse order of ray-finned fishes within the clade Percomorpha. It is part of a sister clade to the Ovalentaria, alongside its sister group, the Anabantaria (including Anabantiformes and Synbranchiformes). The Carangiformes have been long regarded as a monotypic order with only the family Carangidae within it by some authorities, and the other current families within the order have been previously classified as part of the wider order Perciformes. The 5th edition of Fishes of the World classify six families within Carangiformes, with more recent authorities expanding the order to include up to 30 families, based on phylogenetic evidence.
The earliest known carangiforms are two fossil species of Mene, Mene purydi from Peru and Mene phosphatica from Tunisia, both of which are known from the Late Paleocene.

## Taxonomy

This order has often been either subsumed within Perciformes or used exclusively to refer to families classified within the suborder Carangoidei. However, more recent studies using genetic data have found such a placement to be paraphyletic, and have incorporated many more groups into it, including the highly unusual flatfishes.
This classification is from Eschmeyer's Catalog of Fishes Classification.

** Suborder Toxotoidei
*** Family Leptobramidae Ogilby 1913 (beachsalmons)

**** Subfamily Caranginae Rafinesque 1815 (trevallies and kingfishes)
**** Subfamily Scomberoidinae Jordan & Gilbert 1883 (leatherjackets and queenfishes)
**** Subfamily Trachinotinae Gill 1861 (pompanos)
*** Family Echeneidae Rafinesque 1810 (remoras and sharksuckers)
*** Family Rachycentridae Gill 1896 (cobias)
*** Family Coryphaenidae Rafinesque 1815 (dolphinfishes)
The Coryphaenidae, Rachycentridae, and Echeneidae have been suggested to comprise a monophyletic grouping, which has been recovered as a sister clade to the Carangidae. A basal member of this clade is thought to be Ductoridae from the early Eocene.

### Traditional Classification

In past classifications such as Fishes of the World 5, Carangiformes were restricted to these families. This placement is now known to be paraphyletic:
* Nematistiidae Gill (roosterfish)
* Coryphaenidae Rafinesque, 1815 (dolphinfish)
* Rachycentridae Gill 1896 (cobia)
* Echeneidae Rafinesque, 1815 (remoras)
* Carangidae Rafinesque, 1815 (jacks)
* Menidae Fitzinger, 1873 (moonfishes)
