Tor is a genus of cyprinid fish commonly known as mahseers.
Channa is a genus of predatory fish in the family Channidae, commonly known as snakeheads, native to freshwater habitats in Asia. This genus contains about 50 scientifically described species. The genus has a wide natural distribution extending from Iraq in the west, to Indonesia and China in the east, and parts of Siberia in the Far East. A particularly high richness of species exists in Myanmar (Burma) and northeastern India, and many Channa species live nowhere else. In contrast, a few widespread species have been introduced to several regions outside their natural range, where they often become invasive. The large and medium-sized Channa species are among the most common staple food fish in several Asian countries, and they are extensively cultured. Apart from their importance as a food fish, snakeheads are consumed in some regions as a traditional medicine for wound healing and reducing postoperative pain and discomfort, and collected for the international aquarium pet trade.
Ophichthidae is a family of fish in the order Anguilliformes, commonly known as the snake eels. The term "Ophichthidae" comes from Greek ophis ("serpent") and ichthys ("fish"). Snake eels are also burrowing eels. They are named for their physical appearance, as they have long, cylindrical, snake-like bodies. This family is found worldwide in tropical to warm temperate waters. They inhabit a wide range of habitats, from coastal shallows and even rivers, to depths below 800 m (2,600 ft). Most species are bottom dwellers, hiding in mud or sand to capture their prey of crustaceans and small fish, but some are pelagic.
Rasbora is a genus of fish in the family Cyprinidae. They are native to freshwater habitats in South and Southeast Asia, as well as southeast China. A single species, R. gerlachi, is only known from an old specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful. They are small, up to 17 cm (6.7 in) long, although most species do not surpass 10 cm (4 in) and many have a dark horizontal stripe.
Gymnothorax is a genus of fish in the family Muraenidae found in Atlantic, Indian, and Pacific Oceans. With more than 120 species, it the most speciose genus of moray eels.
Myrichthys is a genus of snake eels currently containing 11 recognized species found in tropical and warm temperate oceans worldwide.
Cynoglossus is a genus of fish in the family Cynoglossidae. Most species are indigenous to the Indo-Pacific region, but there are also a few in warmer parts of the East Atlantic. They are commonly found in shallow waters on a muddy or sandy bottom, including estuaries and a few species are restricted to fresh water. One species Cynoglossus sinusarabici has invaded the Mediterranean Sea through the Suez Canal from the Red Sea, a process known as Lessepsian or Erythrean migration.
Moringua is a genus of eels of marine ray-finned fishes belonging to the family Moringuidae, the spaghetti eels. These eels occur in shallow tropical and subtropical waters.
Callechelys is a genus of eels in the snake eel family Ophichthidae. It currently contains the following fifteen species:
Ophichthus is a genus of eels in the snake eel family Ophichthidae.
Yirrkala is a genus of eels in the snake eel family Ophichthidae. It is named after Yirrkala, an indigenous community in Arnhem Land, in the Northern Territory of Australia.
Coilia, the grenadier anchovies, is a genus of anchovies. It currently contains 12–13 species. They are found in East, Southeast and South Asia, and mostly inhabit estuarine regions, but there are also species in coastal marine habitats and rivers. The largest is up to 41 cm (16 in) in length, but most species only reach around half that size.
The ornate snake eel, also known as the sea snake in St. Helena is an eel in the family Ophichthidae. It was described by John Richardson in 1848, originally under the genus Ophisurus. It is a marine, tropical eel which is known from the eastern Atlantic Ocean, including Mauritania, St. Helena, and Ascension Island. It inhabits the continental shelf, where it forms burrows in sand sediments. Males can reach a maximum total length of 90 centimetres (35 in).
The rice-paddy eel is an eel in the family Ophichthidae. It was described by Francis Buchanan-Hamilton in 1822, originally in the genus Ophisurus. It is a tropical, marine eel which is known from the Indo-West Pacific, including Somalia, Tanzania, South Africa, India, Pakistan, Sri Lanka, Indonesia, Polynesia, Australia, Bangladesh, Cambodia, Kenya, Madagascar, the Philippines, Malaysia, Mozambique, Seychelles, Saudi Arabia, Taiwan, China, Thailand, Vietnam, and southern Yemen. It is an anadromous species and spawns in freshwater, often in rice paddies during the rainy season, earning it its common name. It also spends time in lagoons, estuaries and coastal rivers, in which it lives in burrows in the river bottom and bank. Males can reach a maximum total length (TL) of 100 centimetres, but more commonly reach a TL of 70 cm.
The longfin snake-eel is an eel in the family Ophichthidae. It was described by John Richardson in 1848. It has a Dorsal fin beginning above its pectoral fin with a snake-like upper body which is cylindrical, but compressed only along its extreme tail tip. It also has a tubular nostril in front and a nostril along lower edge of the lip in back. Colors range from grey to black to brown. Large longfin snake-eels have wrinkled skin.
Pisodonophis hijala is an eel in the family Ophichthidae. It was described by Francis Buchanan-Hamilton in 1822, originally under the genus Ophisurus. It is a marine, tropical eel which is known from the Indo-Pacific.
Hoeven's snake eel is an eel in the family Ophichthidae. It was described by Pieter Bleeker in 1853, originally under the genus Ophisurus. It is a marine, tropical eel which is known from three specimens found in the Indo-Western Pacific, including Sulawesi, Indonesia, the Persian Gulf and the Gulf of Oman. It is known to inhabit shallow water and lagoons. Males are known to reach a total length of 22 centimetres (8.7 in).
Pisodonophis hypselopterus is an eel in the family Ophichthidae. It was described by Pieter Bleeker in 1851, originally under the genus Ophisurus. It is a tropical, freshwater and brackish water-dwelling eel which is known from Borneo, Indonesia, and Pohnpei in Asia. Males can reach a maximum total length of 75 centimetres (30 in).
Pisodonophis semicinctus is an eel in the family Ophichthidae. First described by John Richardson in 1848., it is a marine, subtropical eel which is known in the eastern Atlantic Ocean from Gibraltar to Angola. It was first recorded in the Mediterranean Sea in 1958 off Algeria and is now found on both shores of the western Basin. It dwells at a depth range of 10 to 30 m and inhabits the continental shelf, where it forms burrows in sand and mud. Males can reach a maximum total length of 80 cm, but more commonly reach a TL of 60 cm.
