|Toothed river herring|
(E. P. Ramsay & J. D. Ogilby, 1886)
The toothed river herring or Papuan river sprat (Clupeoides papuensis) is a species of fish in the Clupeidae family. It is found in New Guinea.
Fish are gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered paraphyletic by excluding the tetrapods. Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology, unless it is used in the cladistic sense, including tetrapods. The traditional term pisces is considered a typological, but not a phylogenetic classification.
Clupeidae is a family of ray-finned fishes, comprising, for instance, the herrings, shads, sardines, hilsa, and menhadens. The clupeoids include many of the most important food fishes in the world, and are also commonly caught for production of fish oil and fish meal. Many members of the family have a body protected with shiny cycloid scales, a single dorsal fin, with a fusiform body for quick, evasive swimming and pursuit of prey composed of small planktonic animals. Due to their small size, and position in the lower trophic level of many marine food webs, the levels of methylmercury they bioaccumulate are very low, reducing the risk of mercury poisoning when consumed.
New Guinea is a large island separated by a shallow sea from the rest of the Australian continent. It is the world's second-largest, after Greenland, covering a land area of 785,753 km2 (303,381 sq mi), and the largest wholly or partly within the Southern Hemisphere and Oceania.
Herring are forage fish, mostly belonging to the family Clupeidae.
The Chao Phraya is the major river in Thailand, with its low alluvial plain forming the centre of the country. It flows through Bangkok and then into the Gulf of Thailand.
Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. Their evolution dates back to the Triassic some 245 to 208 million years ago. The family is grouped into four genera: Acipenser, Huso, Scaphirhynchus and Pseudoscaphirhynchus. Four species may now be extinct. Two closely related species, Polyodon spathula and Psephurus gladius are of the same order, Acipenseriformes, but are in the family Polyodontidae and are not considered to be "true" sturgeons. Both sturgeons and paddlefish have been referred to as "primitive fishes" because their morphological characteristics have remained relatively unchanged since the earliest fossil record. Sturgeons are native to subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America.
The denticle herring is a small, up to 15 cm (5.9 in) long, species of ray-finned fish found only in the rivers of Benin, Nigeria, and western Cameroon. It is related to the herrings, but notable for its large anal fin and its array of denticle-like scales under the head, which give it almost a furry appearance. It is the sole living member of the family Denticipitidae.
The grayling is a species of freshwater fish in the salmon family Salmonidae. It is the only species of the genus Thymallus native to Europe, where it is widespread from the United Kingdom and France to the Ural Mountains in Russia, but does not occur in the southern parts of the continent. It was introduced to Morocco in 1948, but it does not appear to have become established there.
The Ganges shark is a critically endangered species of requiem shark found in the Ganges River and the Brahmaputra River of Bangladesh and India. It is often confused with the more common bull shark, which also inhabits the Ganges River and is sometimes incorrectly referred to as the Ganges shark. Unlike bull sharks, which need to migrate to salt water to reproduce, species in the genus Glyphis are true river sharks. The genus is currently considered to contain three recent species; genetic evidence has shown that both the Borneo river shark and Irrawaddy river shark should be regarded as synonyms of the Ganges shark, expanding the range of the species to Pakistan, Myanmar, Borneo, and Java. The species remains poorly known and very rare.
The powan is a kind of freshwater whitefish endemic to two lochs in Scotland, Loch Lomond and Loch Eck. It has been successfully introduced in two other sites, Loch Sloy and the Carron Valley Reservoir.
The bala shark, Balantiocheilos melanopterus, also known as the tricolor shark, tricolor sharkminnow, silver shark, or shark minnow, is a fish species of the family Cyprinidae, and is one of the two species in the genus Balantiocheilos. This species is not a true shark, but is commonly so called because of its torpedo-shaped body and large fins. It is endangered because the population decreased by 50% in the last 10 years.
Balantiocheilos is a small genus of cyprinid fish from southeast Asia. It includes two species.
The big-eared mastiff bat is a species of bat in the family Molossidae endemic to Papua New Guinea, known from Gulf Province and Oro Province. It is only known from 11 specimens and it is not easy to survey. It forages in rainforest canopy and roosts in tree hollows. It is likely more widespread than currently known but additional research is needed.
Cinetodus froggatti, known as Froggatt's catfish or smallmouthed salmon catfish, is a species of sea catfish found in West Papua in Indonesia and Papua New Guinea where it is found in the Purari, Fly, Strickland and Digul River systems as well as in the Roper River system of Northwest Territories, Australia.
Clupeoides is a genus of sprats that occur in rivers in Southeast Asia. There are currently four recognized species in the genus.
Ctenochromis pectoralis, the Pangani haplo, is a species of fish in the family Cichlidae. It was originally characterized in the Pangani River of Tanzania, and may also be present in Kenya. It is listed as extinct by IUCN as a result of a 1996 evaluation, but this appears to be incorrect. A more recent IUCN publication stated that this species is not endangered in any way.
Ictalurus australis, the Panuco catfish, is a species of North American freshwater catfish, endemic to the Panuco River basin in Mexico.
Oxylapia is a genus of freshwater fish in the family Cichlidae. It contains the single species Oxylapia polli, known locally as the songatana. It is an endangered species, endemic to the Marolambo Rapids in the Nosivolo River in east-central Madagascar. It is threatened by habitat loss and sedimentation caused by deforestation. The only other single-species cichlid genus in Madagascar is Katria, and it is restricted to the same region as Oxylapia. In 2010, the Nosivolo River was designated as a Ramsar Site. The Oxylapia is the conservation flagship species for the district capital Marolambo.
The bluestripe darter is a species of fish in the perch family, Percidae. It is endemic to Missouri in the United States, where it occurs in the rivers of the Ozarks.
The West African Spanish mackerel is a species of fish in the family Scombridae.
Cirrhinus molitorella is a species of ray-finned fish in the genus Cirrhinus found mainly in southern China and Vietnam.
Angora loach is a species of ray-finned fish in the Nemacheilidae family. It is found in Israel, Jordan, Lebanon, Syria, and Turkey. It is found in Sea of Marmara and Black Sea from Simav east to Kızılırmak River drainages and drainages of Ilgin, Lake Akşehir and Lake Eber.
"Freshwater herring" is a term applied to a wide variety of freshwater fish which resemble herring:
In computing, a Digital Object Identifier or DOI is a persistent identifier or handle used to uniquely identify objects, standardized by the International Organization for Standardization (ISO). An implementation of the Handle System, DOIs are in wide use mainly to identify academic, professional, and government information, such as journal articles, research reports and data sets, and official publications though they also have been used to identify other types of information resources, such as commercial videos.
FishBase is a global species database of fish species. It is the largest and most extensively accessed online database on adult finfish on the web. Over time it has "evolved into a dynamic and versatile ecological tool" that is widely cited in scholarly publications.
