The moonfish of the genus Mene, the sole extant genus of the family Menidae, are disk-shaped fish which bear a vague resemblance to gourami, thanks to their thread-like pelvic fins. Today, the genus is represented only by Mene maculata of the Indo-Pacific, where it is a popular food fish, especially in the Philippines, where it is known as bilong-bilong, chabita, hiwas or tahas.
Argillichthys is an extinct marine lizardfish known from the Lower Eocene. It contains a single species, A. toombsi, from the Ypresian-aged London Clay Formation in England. It is known from a skull. It is thought to be a stem-member of Synodontidae.
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.
Eospinus daniltshenkoi is an extinct tetraodontid bony fish from the Eocene. Its fossils are from the Danata Formation lagerstatten of Ypresian Turkmenistan.
Archaeozeus is an extinct genus of marine ray-finned fish from the Ypresian epoch Fur Formation of Denmark. It contains a single species, A. skamolensis, and is the only member of the family Archaeozeidae. It is considered the most basal member of the order Zeiformes.
Beerichthys is an extinct genus of prehistoric marine ray-finned fish. It contains a single species, B. ingens, that was a member of the Ypresian London Clay fauna of lower Eocene England.
Eothynnus salmonens is an extinct species of prehistoric jackfish that lived during the lower Eocene of what is now the Isle of Sheppey (as a part of the London Clay Lagerstatten. It is known exclusively from some preserved skulls.
Kushlukia is an extinct genus of prehistoric bony fish, closely related to the luvar, that lived during the lower Eocene. K. permira is from Eocene portion of the Danata Formation Lagerstatten, of Turkmenistan. A second, as yet undescribed species is from the Fuller's Earth formation Lagerstatten in the Barmer District, of Ypresian Rajasthan, India.
Aulopopsis is an extinct genus of prehistoric marine ray-finned fish that lived during the lower Eocene. It is considered a relative of lizardfish in the order Aulopiformes, but its exact taxonomic placement is uncertain. Some authorities place it with the Aulopidae, while others place it with the Giganturoidae.
Argilloberyx is an extinct genus of prehistoric marine bony fish that lived during the lower Eocene. It contains one species, A. prestwichae, known from the London Clay Formation on the Isle of Sheppey, United Kingdom. It is considered a member of the family Berycidae.
Aipichthyoides is an extinct genus of prehistoric marine bony fish that lived during the lower Cenomanian in what is now the West Bank. Formerly classified in the Polymixiiformes, it is now thought to be a distant relative of oarfish and opahs.
Ctenocephalichthys is an extinct genus of prehistoric ray-finned fish that lived during the Santonian.
Alloberyx is an extinct genus of prehistoric marine ray-finned fish, possibly a holocentrid, that lived during the Santonian of Lebanon. It contains a single species, A. syriacus, initially described as a species of Pseudoberyx.
Adriacentrus is an extinct genus of prehistoric marine bony fish that lived in the Turonian in what is now Croatia. It contains a single species, A. crnolataci. Formerly considered a beryciform fish, it is now known to be more closely related to the squirrelfish (Holocentridae).
Africentrum is an extinct genus of prehistoric soldierfish that lived during the Upper Miocene subepoch of what is now Malta. It contains a single species, A. melitense. It has been either recovered as the sister genus to Myripristis or in a polytomy with all the other genera in the subfamily.
Eotetraodon is an extinct genus of prehistoric pufferfish that lived during the Lutetian epoch of middle Eocene. Fossil specimens are from the Monte Bolca lagerstatten, and the Kuma Horizon of the Gorny Luch locality, from the North Caucasus.
Anguilloides is an extinct genus of prehistoric marine eel that lived in the early Eocene. It contains a single species, A. branchiostegalis. Fossils are known from the famous Monte Bolca site of Italy.
Archaephippus is an extinct genus of prehistoric spadefish that lived from the early Eocene. It contains a single species, A. asper, known from Italy. Several exquisitely preserved fossils have been found from the Monte Bolca lagerstatten. Some juvenile specimens preserve the vertical striped coloration that they would have likely had in life.
Dialipina is an extinct genus of prehistoric, marine osteichthyan. It was initially thought to be an early, basal actinopterygian, but recent phylogenetic analyses suggest that it may instead be a stem-osteichthyan.
Myripristinae is a subfamily of the ray-finned fish family Holocentridae. They are typically known as soldierfish.
