Actinopterygii suborders

Gasterosteoidei is a suborder of ray-finned fishes that includes the sticklebacks and relatives. It belongs to the order Perciformes.

Percoidei is a suborder of bony fishes in the order Perciformes. Many commercially harvested fish species are considered to be contained in this suborder, including the groupers, seabasses and perches.

The Anabantoidei are a suborder of anabantiform ray-finned freshwater fish distinguished by their possession of a lung-like labyrinth organ, which enables them to breathe air. The fish in the Anabantoidei suborder are known as anabantoids or labyrinth fish, or colloquially as gouramies (which more precisely refers to the family Osphronemidae). Some labyrinth fish are important food fish, and many others, such as the Siamese fighting fish and paradise fish, are popular as aquarium fish.

Notothenioidei is one of 19 suborders of the order Perciformes. The group is found mainly in Antarctic and Subantarctic waters, with some species ranging north to southern Australia and southern South America. Notothenioids constitute approximately 90% of the fish biomass in the continental shelf waters surrounding Antarctica.

Zoarcoidei is a suborder of marine ray-finned fishes belonging to the order Perciformes. The suborder includes the wolffishes, gunnels and eelpouts. The suborder includes about 400 species. These fishes are predominantly found in the boreal seas of the Northern Hemisphere but they have colonised the Southern Hemisphere. Many members of this suborder are extremophiles adapted to deepwater ecosystems (including hydrothermal vents) and polar waters.

Scombroidei or Scombrales is a suborder or infraorder of the order Scombriformes or suborder Scombroidei. The suborder or infraorder includes the tunas, mackerel and snake-mackerels. Regular scombrids are observed to have large heads, eyes, and mouths. In most cases, the second dorsal fin will develop before the development of the first.

Stromateoidei or Stromateales is a suborder or infraorder of marine ray-finned fish within the order Scombriformes or suborder Scombroidei. It includes the medusafishes, squaretails and driftfishes which associate with jellyfish, the latter families preying on them while the medusafish use them for protection while scavenging food scraps. It also contains the true butterfish, a common food fish.

Acanthuroidei , is a group of ray finned fishes which is a suborder of the Acanthuriformes, although older classifications regarded it as a suborder of the Perciformes, the largest order of fish, The suborder includes the surgeonfish and Moorish idol. Members of this suborder have a compressed body covered with small ctenoid scales. The name for the suborder comes from that of the surgeonfish (Acanthuridae) family within it, and is derived from the Greek words akantha and oura, which loosely translate to "thorn" and "tail", respectively, referring to the "scalpels" found on surgeonfishes' caud

Scorpaenoidei is a suborder of ray-finned fishes, part of the order Perciformes, that includes the scorpionfishes, lionfishes, stonefishes, sea robins and flatheads. This suborder is at its most diverse in the Pacific and Indian Oceans but is also found in the Atlantic Ocean.

Cottoidei is a suborder of ray-finned fishes in the order Perciformes. It contains sculpins, snailfish, blobfish, greenlings, and sablefish. They are primarily found in temperate, polar, and deep waters, especially in the Northern Hemisphere.

Anguilloidei is a suborder of ray-finned fishes belonging to the order Anguilliformes, the eels.

Syngnathoidei is a large, diverse suborder of syngnathiform fish. It contains the "long-snouted" members of the order, and its monophyly has been affirmed by phylogenetic studies. The order contains pipefish, seahorses, trumpetfish, cornetfish, shrimpfish, and snipefish. They are found in tropical, subtropical and temperate seas, especially in coastal waters around rock and coral reefs and among sea weed and sea grass beds. However, there are also pelagic species of pipefish and even freshwater species.

Channoidei is a suborder of fish in the order Anabantiformes. It contains two families: the true snakeheads (Channidae) and the dragon snakeheads (Aenigmachannidae).

Congroidei is a suborder of ray-finned fishes belonging to the order Anguilliformes, the eels. These eels are mostly marine, although a few species of snake eel will enter freshwater, and they are found in tropical and temperate waters throughout the world.

Clupeoidei is a suborder of marine and freshwater ray-finned fishes belonging to the order Clupeiformes, an order which includes the herrings, anchovies and shads.

Notopteroidei is a suborder of the order Osteoglossiformes that contains the extant families Gymnarchidae (aba), Notopteridae (feather backs and knifefish) and Mormyridae (elephantfishes), as well as several extinct taxa. The Mormyridae are weakly electric fishes, able to locate prey in turbid water.

Muraenoidei is a suborder of mainly marine ray-finned fishes belonging to the order Anguilliformes, the eels. The eels in this suborder are distributed in the tropical and temperate seas around the world.

Cyprinoidei is a suborder, or superfamily, of primarily pelagic, freshwater ray-finned fishes within the larger order Cypriniformes. Many fishes in this group, which are readily found in aquaculture due to their hardiness, include the carps, danionins, and minnows.
