Trichiurus is a genus of cutlassfishes belonging to the family Trichiuridae.
Species within this genus include: [1]
Extinct species within this genus include:
Extinct species lived from the Eocene epoch to the Quaternary period, approximately from 48.6 to 0.012 million years ago. Fossils have been found in the Eocene sediments of Antarctica, Nigeria, United Kingdom, United States, in the Miocene of Costa Rica, India, Mexico, Panama, Slovakia and in the Quaternary of United States.

The cutlassfishes are about 45 species of predatory ray-finned fish in the family Trichiuridae of the order Scombriformes found in seas throughout the world. Fish of this family are long, slender, and generally steely blue or silver in colour, giving rise to their name. They have reduced or absent pelvic and caudal fins, giving them an eel-like appearance, and large fang-like teeth.
The largehead hairtail or beltfish is a member of the cutlassfish family, Trichiuridae. This common to abundant species is found in tropical and temperate oceans throughout the world. The taxonomy is not fully resolved, and the Atlantic, East Pacific and Northwest Pacific populations are also known as Atlantic cutlassfish, Pacific cutlassfish and Japanese cutlassfish, respectively. This predatory, elongated fish supports major fisheries.
The Gempylidae are a family of scombriform ray-finned fishes commonly known as snake mackerels or escolars. The family includes about 25 species.
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.
Wetherellus is an extinct genus of mackerel from the Eocene.
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.
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.
Benthodesmus is a genus of fish in the family Trichiuridae. There are at least eleven species in this genus, which are known as frostfish. These are not to be confused with Microgadus tomcod and Lepidopus caudatus also known as frostfish.
Icichthys is a genus of medusafishes that are native to the eastern Indian Ocean and the northern Pacific Ocean.
Evoxymetopon is a genus of cutlassfish found in all oceans. It is one of nine genera in the family Trichiuridae.
The Savalai hairtail, Lepturacanthus savala, also known as small-head hairtail, is a species of cutlassfish native to the Indian Ocean and into the west Pacific Ocean as far east as Australia. They inhabit deep waters at depths from 100 m (330 ft). The maximum length is 100.0 cm (39.4 in), and weight reaches 11.0 kg (24.3 lb). The fish comes to the surface of the water at night to catch small fish, and crustaceans, especially prawns.
Lepidopus is a genus of cutlassfishes.
Eupleurogrammus is a genus of cutlassfish from the Indo-Pacific region. They are benthopelagic fishes which occur mainly over the continental shelf where they move upwards in the water column towards the surface at night and feed on small fishes, squid and crustaceans. They have very elongated and highly compressed bodies which tapers towards a posterior point.
The New Guinea hairtail is a species of cutlassfish which is classified in the monotypic genus Demissolinea. It is known only from the type location Dolak Island off southwestern New Guinea.
Lepturacanthus is a genus of cutlassfish from the Indo-Pacific region. They are benthopelagic species of waters over the continental shelf, it is a predator of a variety of small coastal fishes, squid and crustaceans.
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.
