Lepidopus is a genus of fishes belonging to the family Trichiuridae. [1]
These fishes lived from the Oligocene to Quaternary (from 33.9 to 1.806 million years ago). Fossils have been found in Italy, Cyprus, Greece, Azerbaijan, the Czech Republic, Germany and Hungary. [2]
Species within this genus include: [3]
Osteichthyes, popularly referred to as the bony fish, is a diverse taxonomic group of fish that have skeletons primarily composed of bone tissue. They can be contrasted with the Chondrichthyes, which have skeletons primarily composed of cartilage. The vast majority of fish are members of Osteichthyes, which is an extremely diverse and abundant group consisting of 45 orders, and over 435 families and 28,000 species. It is the largest class of vertebrates in existence today. The group Osteichthyes is divided into the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii). The oldest known fossils of bony fish are about 420 million years old, which are also transitional fossils, showing a tooth pattern that is in between the tooth rows of sharks and bony fishes.
The cutlassfishes are about 45 species of predatory fish in the family Trichiuridae of the order Perciformes 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.
Hirundichthys is a genus of flying fish. They have elongated, moderately thick, ventrally flattened bodies. The pectoral branch of the lateral line is absent. The upper jaw is not protrusible. The dorsal fin has fewer or equal rays than the anal fin; the dorsal fin is low, with the anterior rays the longest, the pectoral fins are strikingly long, reaching to or almost to caudal fin base; pelvic fins are long, reaching beyond the anal fin origin, and their insertion is closer to the anal fin origin than to the pectoral fin insertion.
The silver scabbardfish, also known as the frostfish or beltfish is a benthopelagic cutlassfish of the family Trichiuridae found throughout the temperate seas of the world. It grows to over 2 metres in length.
The black scabbardfish is a bathypelagic cutlassfish of the family Trichiuridae found in the Atlantic Ocean between latitudes 69°N and 27°N at depths between 180 and 1,700 m. Its length is up to 110 cm (3.6 ft), but it reaches maturity around 80 to 85 cm.
Pseudotrichonotus is a genus of fish in the family Pseudotrichonotidae native to the Indian and Pacific Ocean. This genus is the only member of its family.
The razorback scabbardfish, Assurger anzac, is a rare species of cutlassfish, family Trichiuridae, and the only member of its genus. It has been caught from scattered locations worldwide: in the Atlantic Ocean it is known from off Puerto Rico, Uruguay, and the Walvis Ridge, in the Indian Ocean it is known from off western Australia, and in the Pacific Ocean it is known from off New Guinea, southern Japan, Midway Island, California, and the Nazca and Sala y Gomez Ridges. Adults are thought to be benthopelagic, occurring at a depth of 150–400 meters (490–1,310 ft), while juveniles are found near the surface or in midwater.
Epigonus is a genus of fish in the family Epigonidae found in the Atlantic, Indian and Pacific Ocean. The genus was erected by Constantine Samuel Rafinesque in 1810.
The molly miller is a species of fish of the family Blenniidae in the order Perciformes. It can be found in the Atlantic, Mediterranean, and northwest Pacific Oceans. Its color is a mottled tan, white, and black covering the body and fins. The head of this fish is covered with short hair-like appendages and has two very large eyes. This species reaches 12 cm (4.7 in) in total length.
Aphanopus, the black scabbardfishes, is a genus of Cutlassfish which contains the following species:
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.
Caristius is a genus of manefishes native to the Atlantic and Pacific Oceans.
Platyberyx is a genus of manefishes native to the eastern Atlantic Ocean.
Opecoelidae is a family of trematodes. It is the largest digenean family with over 90 genera and nearly 900 species, almost solely found in marine and freshwater teleost fishes. It was considered by Bray et al. to belong in the superfamily Opecoeloidea Ozaki, 1925 or the Brachycladioidea Odhner, 1905.
Lepidoperca is a small genus of fish belonging to the Anthiinae subfamily. It includes ten species.
Pentaceros is a genus of marine ray-finned fish, armorheads from the family Pentacerotidae. They are native to the Pacific, Indian, and eastern Atlantic Oceans. Pentaceros is the only genus in the monotypic subfamily Pentacerotinae.
Evoxymetopon is a genus of cutlassfish found in all oceans. It is one of nine genera in the family Trichiuridae.
Tentoriceps is a monotypic genus of cutlassfish, family Trichiuridae, from the Indian and Pacific Oceans. The sole species is Tentoriceps cristatus. Its common name is crested hairtail.
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.
