Pristigenys is a genus of marine ray-finned fish in the family Priacanthidae. It contains five extant species and one extinct species, P. substriata, which is known from fossils found in the Eocene of Monte Bolca, Italy. [4]
The extant species have been classified in the genus Pseudopriacanthus which both Fishbase and the Catalog of Fishes treat as a synonym of Pristigenys, [3] but recent work has argued that they should be separated based on numerous differences in the cranial region and the fins. [4] [5]
The following species are classified in the genus Pristigenys: [6] [4]
The butterflyfish are a group of conspicuous tropical marine fish of the family Chaetodontidae; the bannerfish and coralfish are also included in this group. The approximately 129 species in 12 genera are found mostly on the reefs of the Atlantic, Indian, and Pacific Oceans. A number of species pairs occur in the Indian and Pacific Oceans, members of the huge genus Chaetodon.
The Priacanthidae, the bigeyes, are a family of 18 species of marine ray-finned fishes. "Catalufa" is an alternate common name for some members of the Priacanthidae. The etymology of the scientific name refers to the family's very rough, spined scales. The common name of "bigeye" refers to the member species' unusually large eyes, suited to their carnivorous and nocturnal lifestyles. Priacanthidae are typically colored bright red, but some have patterns in silver, dusky brown, or black. Most species reach a maximum total length of about 30 cm (12 in), although in a few species lengths of over 50 cm (20 in) are known.
Handfish are any anglerfish within the family Brachionichthyidae, a group which comprises five genera and 14 extant species. These benthic marine fish are unusual in the way they propel themselves by walking on the sea floor rather than swimming.
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.
Urolophus is a genus of round rays mostly native to the western Pacific Ocean and the Indian Ocean, though one species occurs in the Pacific waters of the Mexican coast. Müller and Henle erected Urolophus in an 1837 issue of Bericht Akademie der Wissenschaften zu Berlin. The name is derived from the Greek oura, meaning "tail", and lophos, meaning "crest". In Urolophus, the outer rims of the nostrils are not enlarged into lobes, but may form a small knob at the back.
Eospinus daniltshenkoi is an extinct tetraodontid bony fish from the Eocene. Its fossils are from the Danata Formation lagerstatten of Ypresian Turkmenistan.
Heteropriacanthus, the glasseyes or glass bigeyes, are a genus of the bigeye family found in all tropical seas around the world. It occasionally makes its way into the aquarium trade. It grows to a size of 50.7 cm (20.0 in) in total length.
The popeye catalufa, also known as the bigeye soldierfish, is a species of marine ray-finned fish in the family Priacanthidae, the bigeyes. This fish has an overall dusky orange to red colour with white markings. The dorsal fin appears feathery while rest of fins have black margins. It occurs in the eastern Pacific, where it is found from Oregon to Chile. It occasionally makes its way into the aquarium trade. It grows to a size of 34 centimetres (13 in) in length. This species is nocturnal and shy, preferring deeper waters off islands. It has been recorded associating with squirrelfishes and cardinalfishes but the popeye catalufa goes as deep as 76 metres (249 ft), deeper than its associated species. This species has been recorded from rocky habitats at depths of less than 5 metres (16 ft) to over 100 metres (330 ft). It is a carnivorous species and, when kept in captivity, is known to feed on worms, crustaceans and brittle stars.
Palaeobalistum is an extinct genus of prehistoric ray-finned fish which ranged from the Cretaceous to Eocene periods.
Pristigenys alta, the toro or short bigeye, is a species of fish in the family Priacanthidae. Some anglers refer to this fish as "toro snapper", but it is not a snapper, and only distantly related to the fish of the snapper family.
Priacanthus hamrur, the lunar-tailed bigeye, goggle eye, or moontail bullseye, is a species of marine fishes belonging to the family Priacanthidae.
Cookeolus japonicus is a species of fish in the family Priacanthidae, the bigeyes and catalufas. It is the only extant species of Cookeolus, except for C. spinolacrymatus, an extinct Late Pliocene fish known from a fossil specimen collected in Okinawa, Japan.
Pristigenys niphonia, the Japanese bigeye, is a species of marine ray-finned fish in the family Priacanthidae. It occurs in the western Pacific Ocean.
Priacanthus is a genus of marine ray-finned fishes belonging to the family Priacanthidae, the bigeyes. As of 2012 there are 12 species in the genus.
Priacanthus sagittarius, The arrow bulleye, is a species of marine ray finned fish, a bigeye in the family Priacanthidae. It is native to the Indian and Pacific Oceans. It is also observed since 2009, in rare occasions, in the eastern Mediterranean Sea, which it most likely entered via the Suez Canal.
Lophius brachysomus is an extinct species of anglerfish in the family Lophiidae. It was described by Louis Agassiz in 1835 from the Monte Bolca locality. It became extinct during the middle Eocene.
This list of fossil fishes described in 2020 is a list of new taxa of jawless vertebrates, placoderms, acanthodians, fossil cartilaginous fishes, bony fishes, and other fishes of every kind that were described during the year 2020, as well as other significant discoveries and events related to paleoichthyology that occurred in 2020.
Arechia is an extinct genus of stingaree from the Eocene epoch. It is the oldest known stingaree genus, though molecular data suggests they diverged from Butterfly rays about 75 million years ago or from Deepwater stingrays around the time of the K-Pg transition. The type species, A. arambourgi, is known from isolated teeth found in the Ypresian deposits of Ouled Abdoun, Morocco. It is named for Camille Arambourg, who originally ascribed these teeth to Raja praealba in 1952. Henri Cappetta revised the species in 1983, erecting this genus for those Arambourg called males in this genus and placed the ones he called females in Merabatis. The second species, A. crassicaudata is from the Ypresian-age Bolca Lagerstätte of Italy and is known from several articulated individuals. This species was described in 1818 and was placed in various genera until finally being attributed to this one in 2020. The inferred environment of the Monte Postale site where this species is found matches with the typical warm, shallow environment of extant representatives of this family.
Cookeolus is a genus of marine ray-finned fishes from the family Priacanthidae, the bigeyes. It contains one extant species and one extinct species.
