Hemimyzon yaotanensis is a species of ray-finned fish in the genus Hemimyzon .
The Hemimyzon yaotanensis is known to be found in a freshwater environment within a demersal range. [1] They are native to a temperate climate. The average length of a Hemimyzon yaotanensis as an unsexed male is about 8.4 centimeters or about 3.3 inches. [2] This species can be found in the areas of Asia, Jinsha-jiang basin in Sichuan, and China. [3]
Balitoridae, the hillstream loaches or river loaches, is a family, of small fish from South, Southeast and East Asia. The family includes about 202 species. They are sometimes sold as "lizardfish" or "flossensaugers". Many of the species are popular for aquaria, species in the genus Sewellia are most commonly sold in the aquaria trade. They have a number of similarities with the Cobitidae, their sibling family of "loaches", such as multiple barbels around the mouth. They should not be confused with the loricariids, which look similar but are a family of catfish.
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.
The Beryciformes are a poorly-understood 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 2,000 m (6,600 ft). 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 8–61 cm (3.1–24.0 in). Member genera include the alfonsinos, squirrelfishes, flashlight fishes, fangtooth fishes, spinyfins, pineconefishes, redfishes, roughies, and slimeheads. A number of member species are caught commercially, including the alfonsino, the splendid alfonsino, and the orange roughy, the latter being much more economically important. Some species have bioluminescent bacteria contained in pockets of skin or in light organs near the eyes, including the anomalopids and monocentrids.
The Khone Falls and Pha Pheng Falls together form a waterfall located in Champasak Province on the Mekong River in southern Laos, near the border with Cambodia. It is the widest waterfall in the world at 10,783 metres in width from one edge of its multiple channels to the other.
Hemimyzon taitungensis is a species of ray-finned fish in the family Balitoridae that is endemic to Taiwan. It is a small freshwater fish currently known only from running waters of the Central Mountain Range of Taiwan at high and middle elevations. In contrast to H. formosanus, it appears to be a well-defined species with no signs of strong genetic structuring suggestive of cryptic species.
Hemimyzon is a genus of freshwater ray-finned fish belonging to the family Balitoridae, the river or hillstream loaches. The species in this genus are found in eastern Asia.
Several species of fish are claimed to produce hallucinogenic effects when consumed, a condition known as ichthyoallyeinotoxism. For example, Sarpa salpa, a species of sea bream referred to as the "dream-fish", is commonly claimed to be hallucinogenic. These widely distributed coastal fish are normally found in the Mediterranean and around the Iberian Peninsula, west to the Azores and along the west and south coasts of Africa. Occasionally they are found in British or more northerly waters. They may induce hallucinogenic effects similar to LSD if eaten. However, based on the reports of exposure they are more likely to resemble hallucinogenic effects of deliriants than the effects of serotonergic psychedelics such as LSD. In 2006, two men who apparently ate the fish experienced hallucinations lasting for several days. The likelihood of hallucinations depends on the season. Sarpa salpa is known as "the fish that makes dreams" in Arabic.
Hemimyzon confluens is a species of ray-finned fish in the genus Hemimyzon. It is known from a single location in the Nam Ngum drainage in Laos, a tributary of the Mekong. The known material suggests a maximum standard length of about 47 mm (1.9 in). H. confluens is threatened by pollution from mining activities and hydro-power development.
Hemimyzon ecdyonuroides is a species of hillstream loach in the genus Hemimyzon. It is known from two tributaries of the Mekong, from Sekong River and Sesan River drainages in Vietnam and Laos.
Hemimyzon formosanus is a species of hillstream loach in the genus Hemimyzon. It is endemic to western portion of Central Mountain Range of Taiwan. Its maximum length is 10 cm (3.9 in). Variations in nucleotide sequences within the mitochondrial control region show strong geographic structuring suggestive of a cryptic species complex.
Hemimyzon khonensis is a species of hillstream loach in the genus Hemimyzon. It is known from a single specimen collected in the Mekong at the Khone Falls in Laos, near the Cambodian border; it is named for the falls. The specimen was 51 mm (2.0 in) in standard length.
Hemimyzon macroptera is a species of hillstream loach in the genus Hemimyzon. It is found in clear-water streams with rocky bottom in the Nanpan River basin, Yunnan, China. It is naturally scarce but widespread.
Hemimyzon pumilicorpora is a species of ray-finned fish in the genus Hemimyzon. it is a fresh water fish found in China. Males can reach up to 5.7 cm in length.
Hemimyzon pengi is a species of ray-finned fish in the genus Hemimyzon. Hemimyzon pengi is a freshwater fish, mainly found in China.
Hemimyzon papilio is a species of ray-finned fish in the genus Hemimyzon.
Hemimyzon sheni is a species of ray-finned fish in the genus Hemimyzon. It is only known from Tar-Ju River basin, Taitung County, southeast Taiwan, where its type locality is. Only three specimens were collected and later attempts to find more specimens have failed. Among its relatives, H. sheni most closely resembles H. formosanus, but it seems to be more a head-water species than H. formosanus. It is a small species with standard length of 5 cm (2.0 in).
Hemimyzon elongata is a species of ray-finned fish in the genus Hemimyzon. It has been found in the Mekong basin in Yunnan, China. It is a benthopelagic, freshwater fish.
Hemimyzon tchangi is a species of ray-finned fish in the genus Hemimyzon.
SeaLifeBase is a global online database of information about marine life. It aims to provide key information on the taxonomy, distribution and ecology of all marine species in the world apart from finfish. SeaLifeBase is in partnership with the WorldFish Center in Malaysia and the UBC Institute for the Oceans and Fisheries at the University of British Columbia. Daniel Pauly is the principal investigator and it is coordinated by Maria Lourdes D. Palomares. As of March 2023, it included descriptions of 85,000 species, 59,400 common names, 15,500 pictures, and references to 39,300 works in the scientific literature. SeaLifeBase complements FishBase, which provides parallel information for finfish.
Acinocheirodon melanogramma is a species of characin endemic to Brazil, where it is found in the São Francisco and Jequitinhonha Rivers. It is the only member of its genus. It can be found in freshwater environments at a benthopelagic depth range. They are native to a tropical climate. The average length of an unsexed male is about 3.8 cm. They are distributed in the São Francisco and Jequitinhonha River basins of Brazil. This species prefer to live in fresh water with a moderate current. They have one row of teeth in the upper and lower jaw. The common names of A. melanogramma in Brazil are pequira, piabinha, and lambari.
