Perciformes in the context of "Perch"

Squamata (/skwæˈmeɪtə/, Latin squamatus, 'scaly, having scales') is the largest order of reptiles; most members of which are commonly known as lizards, with the group also including snakes. With over 11,991 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish. Squamates are distinguished by their skins, which bear horny scales or shields, and must periodically engage in molting. They also possess movable quadrate bones, making possible movement of the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very widely to accommodate comparatively large prey. Squamates are the most variably sized living reptiles, ranging from the 16 mm (0.63 in) dwarf gecko (Sphaerodactylus ariasae) to the 6.5 m (21 ft) reticulated python (Malayopython reticulatus). The now-extinct mosasaurs reached lengths over 14 m (46 ft).

Among other reptiles, squamates are most closely related to the tuatara, the last surviving member of the once diverse Rhynchocephalia, with both groups being placed in the superorder Lepidosauria.

Jordaniidae is a small family of marine ray-finned fishes belonging to the order Perciformes. These fishes are found in the eastern North Pacific Ocean.

A sculpin is a type of fish that belongs to the superfamily Cottoidea in the order Perciformes. As of 2025, this superfamily contains 5 families, 112 genera, and 405 species.

Sculpins occur in many types of habitat, including ocean and freshwater zones. They live in rivers, submarine canyons, kelp forests, and shallow littoral habitat types, such as tidepools.

Percomorpha (from Latin perca 'perch' and Ancient Greek 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.

Anthias are members of the family Anthiadidae in the order Perciformes. The group has also been called Anthiidae or Anthiinae, but these names are preoccupied by a subfamily of ground beetles in the family Carabidae erected by Bonelli in 1813.

Anthias are mostly small, thus are quite popular within the ornamental fish trade. They form complex social structures based on the number of males and females and also their position on the reef itself, and are mainly zooplankton feeders. They occur in all tropical oceans and seas of the world. The first species recognized in this group was described in the Mediterranean and northeast Atlantic and was given name Anthias anthias by Carl Linnaeus in 1758.

Serranidae is a family of marine fish belonging to the order Perciformes. The family used to contain about 450 species in 65 genera, including some of the sea basses and groupers, but taxonomic revisions split out Epinephelinae (groupers), Grammistini (soapfish), and Anthiadinae (anthias); as a consequence, this family is now much less speciose. Representatives of this group live in tropical and subtropical seas worldwide.

Groupers are a diverse group of marine ray-finned fish in the family Epinephelidae, in the order Perciformes.

Groupers were long considered a subfamily of the seabasses in Serranidae, but are now treated as distinct. Not all members of this family are called "groupers". The common name "grouper" is usually given to fish in one of two large genera: Epinephelus and Mycteroperca. In addition, the species classified in the small genera Anyperidon, Cromileptes, Dermatolepis, Graciela, Saloptia, and Triso are also called "groupers". Fish in the genus Plectropomus are referred to as "coral groupers". These genera are all classified in the subfamily Epiphelinae. However, some of the hamlets (genus Alphestes), the hinds (genus Cephalopholis), the lyretails (genus Variola), and some other small genera (Gonioplectrus, Niphon, Paranthias) are also in this subfamily, and occasional species in other serranid genera have common names involving the word "grouper". Nonetheless, the word "grouper" on its own is usually taken as meaning the family Epinephelidae.

Pomacentridae is a family of ray-finned fish, comprising the damselfishes and clownfishes. This family were formerly placed in the order Perciformes or as indeterminate percomorphs, but are now considered basal blenniiforms.They are primarily marine, while a few species inhabit freshwater and brackish environments (e.g., Neopomacentrus aquadulcis, N. taeniurus, Pomacentrus taeniometopon, Stegastes otophorus). They are noted for their hardy constitutions and territoriality. Many are brightly colored, so they are popular in aquaria.

Centrarchiformes /sɛnˈtrɑːrkɪfɔːrmiːz/ is an order of ray-finned fish, previously included amongst the perciformes. The order Centrarchiformes is not recognized in the 5th Edition (2016) of Fishes of the World, but is accepted on the World Register of Marine Species in November 2023, Fishbase, and Eschmeyer's Catalog of Fishes.

Many centrarchiforms look essentially perch-like, featuring a stocky build and a spine-bearing dorsal fin, and range in size from 2.5 cm (0.98 in) in length (for Elassoma gilberti), to 1.8 m (5.9 ft) for the Maccullochella peelii.
