Tetraodontiformes, also known as the Plectognathi, is an order of ray-finned fishes which includes the pufferfishes and related taxa. This order has been classified as a suborder of the order Perciformes, although recent studies have found that it, as the Tetraodontoidei, is a sister taxon to the anglerfish order Lophiiformes, called Lophiodei, and have placed both taxa within the Acanthuriformes. The Tetraodontiformes are represented by 10 extant families and at around 430 species overall. The majority of the species within this order are marine but a few may be found in freshwater. They are found throughout the world.
The Latidae, known as the lates perches, are a family of perch-like fish found in Africa, Asia, and the Indian and western Pacific Oceans. Including about 13 species, the family, previously classified subfamily Latinae in family Centropomidae, was raised to family status in 2004 after a cladistic analysis showed the original Centropomidae were paraphyletic.
Drepane is a genus of marine and brackish water ray-finned fishes, known commonly as the sicklefishes. It is the only genus in the monotypic percomorph family Drepaneidae. These fish occur in the Indian and western Pacific Oceans, and in the eastern Atlantic near Africa.
Ceratiidae, the warty sea devils, caruncled seadevils or seadevils, are a family of marine ray-finned fishes belonging to the suborder Ceratioidei, the deep-sea anglerfishes, in the anglerfish order Lophiiformes. The warty sea devils are sexually dimorphic with the small males being obligate sexual parasites of the much larger females. The fishes in this family are widely distributed from polar to tropical seas around the world.
Double anglers, the family Diceratiidae, is a small and little known family of rarely encountered marine ray-finned fishes belonging to the order Lophiiformes, the anglerfishes. The two genera and seven species of this family are found in the deeper waters of the tropical and subtropical Atlantic, Indian and Pacific Oceans. They are distinguished from other deep sea anglerfishes by the possession of a second bioluminescent cephalic spine. The fishes in this family were known only from metamorphosed females and the males were not described until 1983.
Apistinae, the wasp scorpionfishes, is a subfamily of venomous, marine ray-finned fishes belonging to the family Scorpaenidae, the scorpionfishes and related species. These fishes are native to the Indian Ocean and the western Pacific Ocean.
Triacanthidae, commonly known as triplespines or tripodfishes, is a family of Indo-Pacific fishes. It is classified in the order Tetraodontiformes, along with the pufferfishes and the ocean sunfish. The family consists of seven species in four genera, in addition to three extinct genera that are only known from fossils.
The spikefishes are ray-finned fishes related to the pufferfishes and triggerfishes. They live in deep waters; more than 50 m (160 ft), but above the continental shelves. They are found in the Atlantic, Indian Ocean, and the west-central Pacific.
Cryptobalistes is an extinct genus of triplespine that lived during the early Oligocene epoch. It contains a single species, C. brevis that inhabited the seas around what is now Canton Glarus, Switzerland. It is thought to be closely allied with another triplespine from Glarus, Acanthopleurus. Cryptobalistes, Acanthopleurus, and Protacanthodes are thought to be basal members of the Triacanthidae.
Acanthopleurus is an extinct genus of marine triplespine that lived in the seas over what is now Europe during the early Oligocene epoch.
Acanthurus tractus, the five-band surgeonfish, ocean surgeon, or ocean surgeonfish, is a species of ray-finned fish in the family Acanthuridae found in the western Atlantic Ocean, Florida, the Bahamas, the Caribbean Sea and the Gulf of Mexico. Until recently, it was considered a synonym of Acanthurus bahianus, but its status as a separate species was resurrected in 2011.
Atrophacanthus is a monospecific genus of marine ray-finned fish belonging to the family Triacanthodidae, the spikefishes. The onlu species in the genus is Atrophacanthus japonicus, the upward-mouth spikefish, which is found in the Indo-West Pacific region.
Hollardia is a genus of marine ray-finned fishes belonging to the family Triacanthodidae, the spikefishes. These demersal fishes are found in the Western Atlantic Ocean with one species being found in the Pacific Ocean.
Parahollardia is a genus of marine ray-finned fishes belonging to the family Triacanthodidae, the spikefishes. These demersal fishes are found in the Western Atlantic Ocean.
Bothragonus is a genus of marine ray-finned fishes belonging to the family Agonidae, the poachers and related fishes. It is the only genus in monotypic subfamily Bothragoninae. These fishes are found in the northern Pacific Ocean.
Triglinae is a subfamily of demersal, marine ray-finned fishes, part of the family Triglidae, the gurnards and searobins. These gurnards are found in all the tropical and temperate oceans of the world except for the Western Atlantic Ocean.
Stichaeinae is a subfamily of marine ray-finned fishes, classified within the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific, Arctic and North Atlantic Oceans.
Jordaniidae is a small family of marine ray-finned fishes belonging to the order Scorpaeniformes. These fishes are found in the eastern North Pacific Ocean.
Triacanthoidei is a suborder of ray-finned fishes belonging to the order Tetraodontiformes, which includes the pufferfishes, triggerfishes and related taxa. These benthic fishes are mainly found in the Indian Ocean with some of the spikefishes found in the Western Atlantic Ocean.
Triacanthodinae is a subfamily of marine ray-finned fishes belonging to the family Triacanthodidae, the spikefishes. This subfamily comprises nine genera and a total of nineteen species and all, except one species, are found in the tropical and subtropical waters of the Indo-Pacific. The exception is found in the western Atlantic Ocean.
