Caecocypris basimi, the Haditha cavefish, is a species of cyprinid fish endemic to Iraq, only occurring in aquifers near Haditha. It is found in an underground sinkhole directly under a shrine the only way to access which is a well 5m below the shrine. [2] This cavefish is the only member of its genus. The species is classed as Critically endangered, possibly extinct, by the IUCN, as there have been no records since 1983 despite a comprehensive survey in 2012. [1] The primary threat is water extraction, which has lowered the groundwater level. [1] It is placed as one of the top 10 lost freshwater fishes to be found. [3]
The cavefish Typhlogarra widdowsoni is found in the same place and it has also drastically declined, but it is not as rare as Caecocypris basimi. [1] [4] The only other known cavefish in Iraq is Eidinemacheilus proudlovei. [5]
The holotype of Caecocypris basimi, collected by Dr. Basim M Al Azzawi in 1977, is deposited at the British Museum of Natural History and other specimens are at the Australian Museum. [6]
The red garra, also known as the doctor fish or nibble fish, is a species of cyprinid that is native to a wide range of freshwater habitats in subtropical parts of Western Asia. This small fish typically is up to about 14 centimeters in total length, but locally individuals can reach as much as 24 cm (9.5 in).
The Ozark cavefish, Amblyopsis rosae, is a small subterranean freshwater fish endemic to the United States. It has been listed as a threatened species in the US since 1984; the IUCN currently lists the species as Near Threatened, though it was previously listed as Vulnerable between 1986 and 1996. It is listed as Endangered and Threatened by the Missouri Department of Conservation.
The common nase is a European potamodromous cyprinid fish. It is often simply called the nase, but that can refer to any species of its genus Chondrostoma. Another name is sneep.
Caecobarbus geertsi, the African blind barb or Congo blind barb, is a species of cyprinid fish. This threatened cavefish is only known from Democratic Republic of the Congo, and it is the only member of the monotypic genus Caecobarbus. George Albert Boulenger described this fish in 1921 and it apparently lacks any close relatives in the Congo region.
Garra kemali is a species of cyprinid fish, which is found only in Turkey, in swamps and freshwater lakes. It is threatened by a habitat loss.
Garra typhlops, also known as the Iran cave barb is a species of ray-finned fish in the family Cyprinidae. It is endemic to caves in Iran. Like other cave-adapted fish, it is blind and lacks pigmentation.
Pelecus cultratus, commonly known as the ziege, sichel, sabre carp or sabrefish, is a cyprinid fish species from Eastern Europe and adjacent Asian regions, the only one in its genus, inhabiting the lower reaches of rivers and brackish waters in the eastern Baltic Sea, Black Sea, Caspian Sea and Aral Sea basins. The ziege having no major threats, the IUCN lists it as being of Least Concern.
Phreatichthys andruzzii, a species of cyprinid fish, is the only species of the genus Phreatichthys, and is endemic to Somalia. This cave-adapted fish is whitish and blind. It has no scales. It is considered to have evolved in the cave environment for some two million years. Its name derives from the Greek words phreasatos for spring, and ichthys for fish. It grows to a maximum length of 6.2 cm (2.4 in).
Typhlogarra widdowsoni or Garra widdowsoni, the Iraq blind barb or Haditha cave garra, is a species of cyprinid fish endemic to underground water systems near Haditha in Iraq. Although traditionally placed in its own genus Typhlogarra, this is not supported by genetic evidence, leading to its move to Garra. This cavefish is considered critically endangered because of water extraction, which has lowered the groundwater level. Once abundant, a survey in 2012 found that it now was very rare. Another species from the same place, Caecocypris basimi, may already be extinct. The only other known cavefish in Iraq is Eidinemacheilus proudlovei.
Danio erythromicron, often known as emerald dwarf danio and emerald dwarf rasbora, is a species of cyprinid fish which is endemic to Inle Lake in Myanmar.
Uegitglanis zammaranoi is the only species of catfish in the genus Uegitglanis of the family Clariidae. It is endemic to Somalia, where it only occurs in caves near the Jubba and the Shebelle Rivers. This species grows to about 10.1 cm (4.0 in) in total length.
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish and hypogean fish.
Barilius mesopotamicus, the Mesopotamian minnow or Mesopotamian barilius, is a species of fish in the family Cyprinidae. It is found in rivers, streams and irrigation ditches, usually with some flow and water temperatures from 12 to 24 °C (54–75 °F), in the Tigris-Euphrates basin of Iran, Iraq, Syria and Turkey. It reaches a length of about 7 cm (2.8 in).
The mangar is a large species of ray-finned fish in the genus Luciobarbus, native to the Tigris–Euphrates river system in Iran, Iraq, Syria and Turkey.
Acheilognathus macropterus is a species of cyprinid fish native to China and northern Vietnam. It grows to a length of 27.5 centimetres (10.8 in) SL.
The Nemacheilidae, or stone loaches, are a family of cypriniform fishes that inhabit stream environments, mostly in Eurasia, with one genus, Afronemacheilus found in Africa. The family includes about 790 species.
Eidinemacheilus is a genus of troglobitic fish in the family Nemacheilidae endemic to Iran and Iraqi Kurdistan.
The Mesopotamian barbel or leopard barbel is a species of cyprinid fish found in the Tigris-Euphrates river system in Turkey, Syria, Iraq and Iran. This inhabitant of large rivers has been declining very rapidly during at least the last 30 years. It is now very rare and may be on the brink of extinction. While there are not enough data to identify the actual rate of population decline, it was once locally abundant but now almost absent.
Leuciscus vorax, sometimes known as the Tigris asp or Mesopotamian asp, is a freshwater fish of the Cyprinid family. It is native to the Tigris-Euphrates basin and Orontes River in Iran, Iraq, Syria, and Turkey.
