Nun galilaeus, [3] also known as the Galilean stone loach, is a species of stone loach in the family Nemacheilidae native to Israel and Syria.
Nun galilaeus has the elongated, subcylindrical body shape typical of stone loaches with its mean depth being 15.5% of its length. That of the caudal peduncle being 10.4% while the head makes up a mean of 21.2% of the standard length. The origin of the dorsal fin sits in front of the vertical origin of the pelvic fin. The dorsal fin has a slightly convex to near straight upper margin and 4-5 unbranched and 9-11 branched rays. The anal fin has 3-4 unbranched and 5-6 branched rays. The caudal fin is slightly emarginated, but can look truncated. The body is scaleless and the lateral line extends to the anal fin. The lip is thick and has an irregular outline and there are three pairs of barbels around the mouth, one maxillio-mandibular pair and two rostral pairs. The body colour is generally a light yellowish brown with an irregular pattern of grey brown mottles and a varying number of diffuse bars or blotches which can fuse towards the caudal fin for vertical stripes.

Num galilaeus is known with certainty from two lakes in the drainage basin of the River Jordan, Lake Hula in Israel and the smaller Lake Muzairib in Syria. It has been extirpated from Lake Hula and Lake Muzairib is affected by moderate pollution and a declining water level due to over abstraction and low rainfall. However, the species is said to be still abundant in that lake. It has been reported from a third lake, Lake Tiberias, but that is now thought to be a mislabelled specimen. It is a lake species which can be found near the lake shores. [1] It can also be found in very slow flowing, almost stagnant water in the tributaries to Lake Muzairib where it lives among stones and the roots of willows. [4]
The clown loach, or tiger botia, is a tropical freshwater fish belonging to the botiid loach family. It is the sole member of the genus Chromobotia. It originates in inland waters in Indonesia on the islands of Sumatra and Borneo. In Sentarum, West Borneo that fish named: ulanguli. It is a popular fish in the freshwater aquarium trade and is sold worldwide.
The stone loach is a European species of fresh water ray-finned fish in the family Nemacheilidae. It is one of nineteen species in the genus Barbatula. Stone loaches live amongst the gravel and stones of fast flowing water where they can search for food. The most distinctive feature of this small fish is the presence of barbels around the bottom jaw, which they use to detect their invertebrate prey. The body is a mixture of brown, green and yellow.
Oxynoemacheilus insignis is a species of stone loach It is restricted to the Damascus basin in Syria and to the Jordan-Dead Sea basin in Syria, Israel and Jordan. Its natural habitat is rivers. It is threatened by the drying up of the rivers and streams in which it is found, caused by overuse, damming and less rainfall, as well as by pollution. In Syria it has been extirpated from the Barada and can now only be found in the upper reaches of the Awaj to the west of Damascus. It is a highly variable species and different populations can differ from their neighbouring populations that in the past they have been described as species or subspecies and this has led to a large number of synonyms for Oxynoemacheilus insignis.
Yunnanilus macrogaster is a hypogean species of stone loach endemic to China. This species is endemic to the endorheic drainage system which feeds the Datangzi Marsh in Luoping County, Yunnan, the marsh has been formed by the outflow of a stream from its underground course. It is a demersal species and the waters where it was found were densely vegetated, it feeds on worms and insects. It is sympatric with Yunnanilus niger and Y, paludosus, forming a small species flock. It lays eggs which it does not guard.
The Lake Victoria squeaker is a species of upside-down catfish that is native to Kenya, Burundi, Tanzania and Uganda where it is found in Lakes Kioga and Victoria and the Victorian Nile in the lower Kagera River and the Malagarasi River drainage. It was first described by British-Belgian zoologist George Albert Boulenger in 1906, from specimens collected in the Lake Victoria at Buganga, Uganda and Entebbe, Uganda by Mr. E. Degen. The species name victoriae is derived from the location where the species was originally discovered, Lake Victoria.
Synodontis petricola, known as the cuckoo catfish, or the pygmy leopard catfish, is a species of upside-down catfish endemic to Burundi, Zambia, the Democratic Republic of the Congo, and Tanzania where it is only known from Lake Tanganyika. It was first described by Belgian ichthyologist Hubert Matthes in 1959. The species name "petricola" is derived from a combination of the Latin petra, meaning stone or rock, and the Latin cola, meaning inhabitant. This refers to the rocky environment where this species is found.
Synodontis pardalis is a species of upside-down catfish that is endemic to Cameroon where it occurs in the Dja River drainage. It was first described by British-Belgian zoologist George Albert Boulenger in 1908, from specimens collected in the Dja River in southern Cameroon. The species name pardalis is derived from the Greek word pardalis, which means "leopard", which refers to the spotted pattern on the fish.
Oxynoemacheilus namiri, the Levantine loach, is a species of ray-finned fish in the genus Oxynoemacheilus. This species is common and widespread in the drainage system of the Orontes in Turkey and Syria, as well as in coastal streams in Syria south of the border with Lebanon, where it can be found in springs, reservoirs, streams and rivers.
Oxynoemacheilus bergianus, the Kura sportive loach, is a species of ray-finned fish in the genus Oxynoemacheilus. This species is found in Lake Urumiyeh and Namak Lake basins in Iran, in the southern Caspian basin from Kura east to the Sefid-Rud drainage. It can also be found in the headwaters of Tigris in Turkey, Iraq and in Karoun, Iran as well as those of the Euphrates in Turkey and possibly in Syria and Iraq. It lives in fast flowing streams and rivers with gravel and rocky substrates and does not tolerate impoundments, dam construction having been identified as a major potential threat to this species.
Oxynoemacheilus argyrogramma, the two-spot loach is a species of ray-finned fish in the genus Oxynoemacheilus. This species is found in the drainage of the Queiq River in Syria and Turkey, and the upper Euphrates drainage in Turkey and possibly in this drainage in Syria and Iraq. It has almost been extirpated from the Queiq as this river has virtually dried out but it remains abundant in the Euphrates. This species can be found in a wide range of habitats as long as there is a moderately fast current from small upland streams to banks of large rivers. It can also occur in stagnant water bodies such as reservoirs. It is threatened by water abstraction, lowering rainfall due to climate change and the construction of dams. The economic development of the area where this species occurs exacerbates these threats. Freyhof and Özuluǧ published a paper in 2017 that argued that Oxynoemacheilus euphraticus was a valid species and not a synonym of O. argyrogramma.
Oxynoemacheilus frenatus, the banded Tigris loach, is a species of ray-finned fish in the genus Oxynoemacheilus. This species is widespread in the upper drainage basin of the Tigris in Turkey, Syria and Iraq where it can be locally very common. It can be found in habitats varying from streams with a moderately fast current to near standing waters in springs, streams and rivers which have beds of gravel or mud. Academically speaking, it inhabits fast-flowing streams and rivers with rocky substrates.
Oxynoemacheilus panthera, the tiger loach or the Damascus loach, is a species of ray-finned fish in the genus Oxynoemacheilus. It occurs in only two streams, the Nahr Baradá and Nahr al-A‘waj in the Damascus basin in Syria. It is thought that over 90% of the populations of this species of stone loach have been lost due to water abstraction and the drying up of its native watercourses, exacerbated by lower rainfall levels.
The scaly sand darter is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to the southeastern United States. It is found in the coastal plain area of the Mississippi River basin, typically in medium-sized streams with slow currents over sandy substrates where it feeds on midge larvae and other small invertebrates. The slender body is semi-translucent, yellowish with a dozen or so dark bars. This fish has a wide range and is relatively common, and the International Union for Conservation of Nature lists it as a "least-concern species".
Noturus flavus, the stonecat, is a North American freshwater catfish of the family Ictaluridae. The common name is due to its habit of hiding near or under stones in fast-moving water.
Deuterodon pelecus is a species of characid fish from Brazil. It can be distinguished from other species by: its body depth ; its short and pointed snout smaller than the orbital diameter; and a reduced number of branched anal fin rays. D. pelecus also differs from members of its genus by its characteristic color pattern. It possesses a single humeral spot that is constricted to the region above the lateral line; at the same time it shows a conspicuous midlateral body stripe from opercle to the caudal fin base, an autapomorphy of this precise species. Other Deuterodon species have a humeral spot that is vertically or horizontally elongate and have the midlateral stripe becoming faint near that humeral spot. The species name is derived from the Greek pelekus, meaning "axe", referring to the pigmentation shape resulting from the adjoinment of the humeral spot with the midlateral stripe.
The Savannah darter is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to the eastern United States, where it occurs in the Edisto, Combahee, Broad and Savannah River drainages in South Carolina and Georgia. It inhabits gravel riffles, gravel and sand runs of creeks and small rivers. This species can reach a length of 7.4 cm (2.9 in).
Schistura callidora is a species of ray-finned fish in the stone loach genus Schistura. It was first found in the Myitnge River drainage, Irrawaddy basin in Myanmar. It is distinguished by possessing dark bars on its body, being much thinner in its anterior half; a high dorsal crest on the caudal peduncle; the number of dorsal-fin rays; and its lateral line which reaches behind the base of the anal fin.
Oxynoemacheilus anatolicus, the Burdur loach, is a species of stone loach in the genus Oxynoemacheilus. It has been only recorded from three spring fed streams which used to drain into Lake Burdur in south-western Anatolia, Turkey. Its habitat is streams with a slow current flowing through dense aquatic vegetation over a bed of sand, mud or gravel. It is still found in the three streams and in one it is said to be abundant but it is still threatened by water extraction, pollution and dam construction. In addition, waterbodies in the area it is found in are drying out because of climate change and unsustainable extraction of water for human use.
Triplophysa daryoae, the Sokh stone loach, is a species of ray-finned fish in the family Nemacheilidae. It is endemic to the Sokh River in Fergana Valley, Uzbekistan. It lives in fast-flowing rivers over 1050m in altitude.
Vaillantella euepiptera is a species of freshwater ray-finned fish, a loach, belonging to the family Vaillantellidae, the longfin loaches. This species is found in Southeast Asia.
