Trachichthyiformes
The Trachichthyiformes are an order of ray-finned fishes in the superorder Acanthopterygii. Fossils of this group date back to the Cenomanian. Member genera include the flashlight fishes, fangtooth fishes, spinyfins, pineconefishes, redfishes, roughies, and slimeheads. A number of member species are caught Commercial fishing, commercially, most notably the orange roughy. Some species have bioluminescent bacteria contained in pockets of skin or in light organs near the eyes, including the anomalopids and monocentrids. Phylogeny A recent phylogeny based on the work of Betancur-Rodriguez ''et al.'' 2017 shows Trachichthyiformes as a sister group of Beryciformes in the clade Berycimorpha.

Acanthopterygii
Acanthopterygii (meaning "spiny-finned one") is a superorder of teleost, bony fishes in the class Actinopterygii. Members of this superorder are sometimes called ray-finned fishes for the characteristic sharp, bony rays in their fins; however this name is often given to the class Actinopterygii as a whole. The suborder includes the Berycidae, berycids and their allies, but by far the largest member of the group is the Percomorpha, the most diverse vertebrate clade. Taxonomy The following taxonomy is based on ECoF (2025), with subseries based on earlier studies: * Series Berycida ** Order Trachichthyiformes, including Monocentridae, pineconefishes, Slimehead, slimeheads & Fangtooth, fangtooths ** Order Beryciformes *** Suborder Holocentridae, Holocentroidei, Holocentrinae, squirrelfish & Myripristinae, soldierfish *** Suborder Berycoidei, Alfonsino, alfonsinos & Berycidae, berycids *** Suborder Stephanoberyciformes, Stephanoberycoidei, Stephanoberycidae, pricklefishes, Cetomim ...

Beryciformes
The Beryciformes are a poorly-understood Order (biology), order of carnivorous ray-finned fishes consisting of 7 families, 30 genera, and 161 species. They feed on small fish and invertebrates. Beyond this, little is known about the biology of most member species because of their nocturnal habits and deepwater habitats. All beryciform species are marine and most live in tropical to temperate, deepwater environments. Most live on the continental shelf and continental slope, with some species being found as deep as . Some species move closer to the surface at night, while others live entirely in shallow water and are nocturnal, hiding in rock crevices and caves during the day. Several species are mesopelagic and bathypelagic. Beryciformes' bodies are deep and mildly compressed, typically with large eyes that help them see in darker waters. Colors range from red to yellow and brown to black, and sizes range from . Member genera include the alfonsinos, squirrelfishes, pricklefishes, ...

Ray-finned Fish Orders
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called ''lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii Sarcopterygii (; )—sometimes considered synonymous with Crossopterygii ()—is a clade (traditionally a class (biology), class or subclass) of vertebrate animals which includes a group of bony fish commonly referred to as lobe-finned fish. The ... (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins.

Percomorpha
Percomorpha () is an extremely large and diverse clade of ray-finned fish. With more than 17,000 known species (including Scombroidei, tuna, Syngnathiformes, seahorses, gobies, Cichlidae, cichlids, flatfish, Labridae, wrasse, Perciformes, perches, Lophiiformes, anglerfish, and Tetraodontiformes, pufferfish) known from both marine and freshwater ecosystems, it is the most speciose clade of extant Vertebrate, vertebrates. Evolution Percomorpha are the most biodiversity, diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoic Era (geology), era. Fossil evidence shows that there was a major increase in size and abundance of teleosts immediately after the mass extinction event at the Cretaceous–Paleogene extinction event, Cretaceous-Paleogene boundary ago. The oldest known percomorph fossils are of the early Tetraodontiformes, tetraodontiforms ''Protriacanthus'' and Cretatriacanthidae from the Santonian to Campanian of Italy and Slov ...

Anomalopidae
Anomalopidae (lanterneye fishes or flashlight fishes) are a family of fish distinguished by bioluminescent organs located underneath their eyes, for which they are named. These light organs contain luminous bacteria and can be "shut off" by the fish using either a dark lid or by being drawn into a pouch. They are used to communicate, attract prey, and evade predators. Flashlight fish are found in tropical ocean waters across the world. They are typically about in size, although some species can reach twice this length. They are nocturnal, feeding at night on small crustaceans. Some species move to shallow waters near coral reef A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Anoplogastridae
Fangtooths are beryciform fish of the family Anoplogastridae (sometimes spelled "Anoplogasteridae") that live in the deep sea. The name is from the Greek , meaning "unarmed", and (), meaning "stomach". With a worldwide distribution in tropical and cold-temperate waters, the family contains only two very similar species in one genus, with no known close relatives. Species The currently recognized species in this genus are: * '' Anoplogaster brachycera'' ( Kotlyar, 1986) (shorthorn fangtooth) * ''Anoplogaster cornuta'' (Valenciennes, 1833) (common fangtooth) Description While named for their disproportionately large, fang-like teeth and unapproachable visage, fangtooths are actually quite small and harmless to humans: the larger of the two species, the common fangtooth, reaches a maximum length of just ; the shorthorn fangtooth is less than half this size though currently known only from juvenile specimens. ''Anoplogaster cornuta'' are in the smaller size range of fishes. They a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cetomimidae
Cetomimidae is a family of small, deep-sea beryciform ray-finned fish. They are among the most deep-living fish known, with some species recorded at depths in excess of . Females are known as flabby whalefishes, Males are known as bignose fishes, while juveniles are known as tapetails and were formerly thought to be in a separate family, dubbed Mirapinnidae. Adults exhibit extreme sexual dimorphism, and the adult males were once thought to be exemplars of still another family, Megalomycteridae. Thought to have a circumglobal distribution throughout the Southern Hemisphere, Cetomimidae are the most diverse family of whalefishes. The largest species, ''Gyrinomimus grahami'', reaches a length of some 40 cm, though most species average around 20 cm. They are distinguished from other whalefishes by their loose, scaleless skin and lack of photophores. Description Living at extreme, lightless depths, adult females have evolved an exceptionally well-developed lateral line s ...

Holocentridae
Holocentridae is a family of ray-finned fish, the only family of the suborder Holocentroidei and the only family of the order Holocentriformes. The members of the subfamily Holocentrinae are typically known as squirrelfish, while the members of Myripristinae typically are known as soldierfish.Lieske, Ewald, & Robert Myers. 1999. ''Coral Reef Fishes - Caribbean, Indian Ocean, and Pacific Ocean including the Red Sea.'' 2nd edition. In Hawaii, they are known by the Japanese name or the Hawaiian . They are found in tropical parts of the Indian, Pacific and Atlantic Oceans, with the greatest species richness near reefs in the Indo-Pacific. Most are found at depths from the shoreline to , but some, notably the members of the genus ''Ostichthys'', are generally found far deeper. Being largely or entirely nocturnal, they have relatively large eyes. During the day, they typically remain hidden in crevices, caves, or under ledges. Red and silvery colours dominate.

Stephanoberycidae, the pricklefishes are a family of fishes in the order Beryciformes. They are found in tropical and subtropical waters of the Atlantic and Pacific Oceans, and to the Indian Ocean off the coast of South Africa. They are deep-water fishes, only living below , and have been found down to . It is thought that they are bathypelagic (deep ocean dwelling) or benthic (bottom dwelling) as they are known to eat crab Crabs are decapod crustaceans of the infraorder Brachyura (meaning "short tailed" in Greek language, Greek), which typically have a very short projecting tail-like abdomen#Arthropoda, abdomen, usually hidden entirely under the Thorax (arthropo ...s.
