Asian Swamp Eel
The Asian swamp eel (''Monopterus albus''), also known as rice eel, ricefield eel, or rice paddy eel, is a commercially important, air-breathing species of fish in the family Synbranchidae. It occurs in East and Southeast Asia, where it is a very common foodstuff sold throughout the region. It has been introduced to two areas near the Everglades in Florida and near Atlanta in Georgia. Taxonomy The Asian swamp eel is a freshwater, eel-like fish belonging to the family Synbranchidae (swamp eels).Nelson, J.S. Fishes of the World. 3rd. New York City: John Wiley & Sons, Inc., 1994. Print. Some work indicates that the species should be split into three geographical clades or cryptic species, although these were not given nomenclatural names, as the taxonomic synonymy was too complex to sort out at the time. The populations in the Ryukyus are distinct, the populations in China and Japan belong to another clade, and the rest, the original ''M. albus'', belong to the third group. Althoug ...

Ophichthys Desilvai
''Ophichthys desilvai'' (lesser swamp eel or Desilvai's blind eel) is a commercially important, air-breathing species of fish in the family Synbranchidae. It is endemic to Sri Lanka and is the only endemic synbranchid from there. Etymology The specific name honours the Sri Lankan herpetologist Pilippu Hewa Don Hemasiri de Silva (b. 1927), who has been director of the National Museums of Ceylon, in recognition to the help and advice he gave to Carl Gans when he was conducting fieldwork in Sri Lanka. Taxonomy It was formerly classified in the genus ''Monopterus'' but a 2020 study reclassified it into the resurrected genus ''Ophichthys'' along with several other former ''Monopterus'' species. Distribution and habitat It is known from swamp areas and paddy fields from the west side of Sri Lanka. Some have been recovered from the Bolgoda swamp, an estuary southwest of Colombo. A 2020 study found specimens in the lowland coastal floodplain on the west side of the island as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rakthamichthys
''Rakthamichthys'' is a genus of swamp eels that are endemic to India. Three species are known from the Western Ghats and one is known from Northeast India. All species live underground, with one species (''R. rongsaw'') having a fossorial lifestyle and three species (''R. digressus'', ''R. roseni'', and ''R. indicus'') being troglobitic in nature. All species display adaptations to this lifestyle, including a bright red coloration and highly reduced eyes. Taxonomy All four species were formerly classified in the genus ''Monopterus'' until a 2020 study found significant genetic and osteological differences between them and the rest of ''Monopterus'', including unique and highly divergent characteristics in the gill arch skeleton. This led to the species being classified in a new genus ''Rakthamichthys'', with "raktham" meaning "blood-red" in Malayalam, as a reference to their distinctive coloration.

Ophichthys Indicus
The Bombay swamp eel (''Ophichthys indicus''), also known as the paytop in Marathi, is a species of fish in the family Synbranchidae. It is endemic to the state of Maharashtra in India. Taxonomy It was at first classified in the genus ''Amphipnous'', but it was later moved to ''Monopterus''. However a 2020 study found it to form a distinct clade with about 4 other species also previously classified in ''Monopterus'', and the genus ''Ophichthys'' was thus revived to contain them. Distribution This species is thought to be endemic to the northern Western Ghats of India, in the state of Maharashtra. It is currently known from 5-10 localities: Robber's Cave and Dhobi Falls in Mahabaleshwar, Kanheri Falls near Kanheri Caves in Mumbai, and the Tamhini and Tail Baila areas in Pune. However, it is thought to occur in other localities as well. Habitat The species inhabits swamps and marshy areas associated with hill streams. During the early part of the monsoon season, adult ...

Rakthamichthys Rongsaw
''Rakthamichthys rongsaw'' is a species of swamp eel discovered in the Khasi Hills in northeast India. The researchers were searching for caecilians, when they uncovered the eel in soil. Taxonomy It was formerly classified in the genus ''Monopterus'' until a 2020 study found it to group with three other subterranean ''Monopterus'' species from the Western Ghats, all of which displayed significant genetic and osteological differences from any other species in ''Monopterus''. Due to this, all species were classified in the new genus ''Rakthamichthys''. Description Only one eel has been identified to date, the specimen was approximately long. The eel is also absent from skin pigmentation and has 92 precaudal and 69 caudal vertebra The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic i . ...

Swamp Eel
The swamp eels (also written "swamp-eels") are a family (Synbranchidae) of freshwater eel-like fishes of the tropics and subtropics. Most species are able to breathe air and typically live in marshes, ponds and damp places, sometimes burying themselves in the mud if the water source dries up. They have various adaptations to suit this lifestyle; they are long and slender, they lack pectoral and pelvic fins, and their dorsal and anal fins are vestigial, making them limbless vertebrates. They lack scales and a swimbladder, and their gills open on the throat in a slit or pore. Oxygen can be absorbed through the lining of the mouth and pharynx, which is rich in blood vessels and acts as a "lung". Although adult swamp eels have virtually no fins, the larvae have large pectoral fins which they use to fan water over their bodies, thus ensuring gas exchange before their adult breathing apparatus develops. When about a fortnight old they shed these fins and assume the adult form. Most spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhlosynbranchus Boueti
The Liberian swamp eel (''Typhlosynbranchus boueti'') is a species of fish in the family Synbranchidae. It is indigenous to Liberia. It has also been found in Sierra Leone, with an unconfirmed report from Côte d'Ivoire. It was first described by Jacques Pellegrin in 1922 as ''Typhlosynbranchus boueti'', but was later moved to ''Monopterus''. However, a 2020 study revived ''Typhlosynbranchus''. Due to the deficiency in data, the species has not been classified with respect to endangerment. Description Liberian swamp eels, like other eels, have an elongated, naked, cylindrical body. The body of the eel tapers to a point and can be described as whip-like. They grow to be at most in length, with the caudal portion (tail end) of the body being approximately of the overall length of the body. The eyes are atrophied and set deep under the skin making them difficult to discern. The teeth are conical and found affixed to the jaw and palate. The gills of the fish open only slightly and ...

Ophichthys
''Ophichthys'' is a genus of swamp eels native to South Asia. They live in freshwater or subterranean habitats, and some have a fossorial lifestyle. Taxonomy All species in this genus were formerly classified in ''Monopterus'', but a 2020 study found them to represent a distinct monophyletic clade from ''Monopterus''. Due to this, the genus name ''Ophichthys'', previously coined by William John Swainson, was revived to be used for them. ''Ophichthys'' was formerly a wastebasket taxon used to lump in many unrelated species of eel-like fish (all of which are classified in separate genera today) and later synonymized with ''Monopterus'' until its resurrection. Species * ''Ophichthys cuchia'' ( F. Hamilton, 1822) (Gangetic swamp eel or Gangetic mud-eel) * ''Ophichthys desilvai'' ( R. M. Bailey & Gans, 1998) (lesser swamp eel or Desilvai's blind eel) * ''Ophichthys fossorius'' ( K. K. Nayar, 1951) (Malabar swampeel) *''Ophichthys hodgarti'' ( B. L. Chaudhuri, 1913) (Indian spag ...
