The ragfish is a ray-finned fish of the northern Pacific Ocean; although classified as a bony fish, its skeleton is mostly cartilage, and the larvae have pelvic fins that disappear as they mature. It is the sole member of the family Icosteidae within the order Scombriformes.
Caristiidae, the manefishes, are a family of scombriform ray-finned fishes which today includes 19 extant species distributed in four genera. Chalcidichthys malacapterygius and Absalomichthys velifer are extinct species in this family from the Upper Miocene of Southern California.
Medusafishes are a family, Centrolophidae, of scombriform ray-finned fishes. The family includes about 31 species. They are found in temperate and tropical waters throughout the world.
Nomeidae, the driftfishes, are a family of scombriform ray-finned fishes found in tropical and subtropical waters throughout the world. The family includes about 16 species. The largest species, such as the Cape fathead, Cubiceps capensis, reach 1 m in length.
Eobothus is an extinct genus of flatfish known from China, India and Europe. Its geological range extend through part of the Eocene: some studies date it to the Ypresian stage, while others date it to the Lutetian.
Scomberomorini is a tribe of ray-finned saltwater bony fishes that is commonly known as the Spanish mackerels, seerfishes or seer fish. This tribe is a subset of the mackerel family (Scombridae) – a family that it shares with three sister tribes, the tunas, mackerels, and bonitos, and the butterfly kingfish. Scomberomorini comprises 21 species across three genera. They are pelagic fish, fast swimmers and predatory in nature, that fight vigorously when caught. They are mainly caught using hooks and lines.
Scombroidei is a suborder of the order Scombriformes. The suborder 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.
Zaphlegulus venturaensis is an extinct, superficially mackerel-like, fish related to the cutlassfish and snake mackerels found off the coast of what is now California during the late Miocene. Z. venturaensis was shorter, but stouter than either of the other two better known genera of the extinct family Zaphlegidae, Thyrsocles and Euzaphleges, which also lived at the same time.
Amphistium paradoxum, the only species classified under the genus Amphistium and the family Amphistiidae, is a fossil fish which has been identified as a Paleogene relative of the flatfish, and as a transitional fossil. In a typical modern flatfish, the head is asymmetric with both eyes on one side of the head. In Amphistium, the transition from the typical symmetric head of a vertebrate is incomplete, with one eye placed near the top of the head.
Evesthes is an extinct genus of prehistoric bony fish that lived during the Upper Miocene subepoch.
Eobuglossus is an extinct genus of prehistoric bony fish that lived from the early to middle Eocene.
Imhoffius is an extinct genus of prehistoric bony fish that lived from the early to middle Eocene.
Turahbuglossus is an extinct genus of prehistoric bony fish that lived from the early to middle Eocene.
Joleaudichthys is an extinct genus of prehistoric flatfish that lived from the early to middle Eocene of Egypt.
Eutrichiurides is an extinct genus of prehistoric cutlass fish.
Pleuronectinae is a subfamily of fish in the family Pleuronectidae, comprising 14 genera and 33 species. Members of the subfamily are demersal carnivores that live in arctic and northern seas.
The slender sole is a species of flatfish in the family Pleuronectidae. It is a demersal fish that lives on bottoms near rocky areas at depths of between 25 and 800 metres. Its native habitat is the eastern Pacific coast, from the mouth of the Alsek River in Alaska in the north to Isla Cedros in Baja California, Mexico in the south. It can reach up to 35 centimetres (14 in) in length.
Euthynnus lineatus, the black skipjack tuna or black skipjack, is a species of ray-finned bony fish in the family Scombridae. It belongs to the tribe Thunnini, better known as the tunas.
Ariommatidae is a family of marine ray-finned fishes which are classified within the suborder Stromateoidei of the order Scombriformes.
Scombriformes, also known as Pelagia and Pelagiaria, is an order of ray-finned fish within the clade Percomorpha. It contains 287 extant species in 16 families, most of which were previously classified under the suborders Scombroidei and Stromateoidei of the order Perciformes.
