The Japanese rice fish also known as the medaka, is a member of genus Oryzias (ricefish), the only genus in the subfamily Oryziinae. This small native of East Asia is a denizen of rice paddies, marshes, ponds, slow-moving streams and tide pools. It is euryhaline, occurring in both brackish and freshwater. It became popular as an aquarium fish because of its hardiness and pleasant coloration: its coloration varies from creamy-white to yellowish in the wild to white, creamy-yellow, or orange in aquarium-bred individuals. Bright yellow, red or green transgenic populations, similar to GloFish, have also been developed, but are banned from sale in the EU. The medaka has been a popular pet since the 17th century in Japan. After fertilization, the female carries her eggs attached anterior to the anal fin for a period before depositing them on plants or similar things.
The Java pipistrelle is a species of pipistrelle bat found in South and Southeast Asia, including Afghanistan, Bangladesh, Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Pakistan, Philippines,Singapore, Thailand, and Vietnam. It favors human habitations. A 2010 research paper from the Philippines regarding the prevalence of coronaviruses in bats tested several Java pipistrelle bats.
The giant moray is a species of moray eel and a species of marine fish in the family Muraenidae. In terms of body mass, it is the largest moray eel; however, the slender giant moray is the largest in terms of body length.
Oryzias celebensis, the Celebes medaka, fish in the family Adrianichthyidae. It is endemic to rivers, streams and lakes on the Indonesian island of Sulawesi and one river in East Timor.
Oryzias is a genus of ricefishes native to fresh and brackish water in east and south Asia. Some species are widespread and the Japanese rice fish is commonly used in science as a model organism, while others have very small ranges and are threatened. They are small, up to 8 cm (3.1 in) long, and most are relatively plain in colour.
Oryzias marmoratus, also known as the marmorated ricefish or marmorated medaka, is a species of fish in the family Adrianichthyidae, from Lake Towuti, Lake Mahalona, Lake Lontoa and associated streams in Sulawesi, Indonesia.
Oryzias matanensis, the Matano ricefish, is a species of fish in the family Adrianichthyidae. It is endemic to Lake Matano in Sulawesi, Indonesia.
The black buntingi is a species of fish in the family Adrianichthyidae. It is endemic to Lake Poso in Sulawesi, Indonesia, here it is a pelagic species found over sand and pebble substrates.
The sharp-jawed buntingi is a species of ricefish in the family Adrianichthyidae. It is endemic to Lake Poso in Sulawesi, Indonesia.
Oryzias profundicola, the yellow-finned medaka or yellow-finned ricefish, is a species of fish in the family Adrianichthyidae.
Oryzias sarasinorum, the Sarasins minnow or Sarasins buntingi, is a species of ricefish in the Adrianichthyidae. It is endemic to Lake Lindu in Lore Lindu National Park, Sulawesi, Indonesia. This species was described as Haplochilus sarasinorum by C.M.L. Popta in 1905 and she named it in honour of the Swiss naturalists and second cousins Paul Sarasin (1856-1929) and Fritz Sarasin (1859-1942), the latter being the collector of the type. Although the IUCN state that the population of this fish is stabled it is threatened by introduced non native fish, common carp, Mozambique tilapia and walking catfish; and a decline in water quality caused by increased agriculture in the lake's catchment which is causing a decline in water quality, it is therefore assessed as Critically Endangered.
Xenodermus javanicus, also known as the Dragon Snake, Javan Tubercle Snake, Javan Mudsnake, or Rough-backed Litter Snake, is a small non-venomous, semi-fossorial Colubrid snake belonging to the monotypic genus Xenodermus. This species is best known for their characteristic dorsal scales and interesting defense mechanism in which they stiffen their entire bodies when threatened. X. javanicus is nocturnal and subsists on a diet of frogs, tadpoles and small fish. While they are known to perish once placed into captivity, some herpetoculturists have been successful in keeping them.
Acrochordus javanicus, commonly known as the elephant trunk snake or the Javan file snake, is a species of snake in the family Acrochordidae, a family which represents a group of primitive non-venomous aquatic snakes. The species is also kept as an exotic pet.
The Java razorfish is a doubtful species of wrasse about which little is known. This fish gets the name "javanicus" from Java, Indonesia, from which the type specimen was supposedly obtained. Also, some fish have been reported to have been spotted in the Red Sea. The validity of this species is questioned pending further studies.
Oryzias mekongensis is a species of fish in the family Adrianichthyidae. It is endemic to the Mekong River Basin in southeast Asia, where found in ditches, canals and ponds.
Oryzias curvinotus or the Hainan medaka is a species of ricefish which is found in Quang Ninh Province in northern Vietnam and Hainan, Guangdong and Hong Kong in southern China. It is found in both fresh and brackish water. This species was described as Aplocheilus curvinotus in 1927 by J.T. Nichols and C.H. Pope with the type locality given as Nodoa, Hainan Island, China.
The Chinese rice fish is a species of fish in the genus Oryzias. This freshwater fish occurs in swamps, stagnant parts of streams, rice fields and marshes, and is up to 3.1 cm (1.2 in) long. It was formerly considered a subspecies of the Japanese rice fish. The natural range of the Chinese rice fish is in East and Southeast Asia, including the Yangtze, Mekong, Irrawaddy, Salween, Red River and Nanpangjiang basins. It has been introduced to Kazakhstan and Russia ; also spreading in the Azov basin and has been discovered in the Obytichna River in Ukraine.
Oryzias dancena or the Indian ricefish are a freshwater–brackish fish species native to the India, Bangladesh, Sri Lanka, Myanmar and Thailand. Their maximum length is only 3.1 centimetres (1.2 in). They are normally found in brackish habitats near the coast, but it lives in fresh water as well. It is not considered threatened. This species was described as Cyprinus dancena by Francis Buchanan-Hamilton in 1822 with the type locality given as "Estuary below Calcutta".
Oryzias carnaticus or the spotted ricefish are a freshwater–brackish fish species native to the India, Bangladesh, Sri Lanka, and Myanmar. Their maximum length is only 3.0 centimetres (1.2 in). They are normally found near the coast, and can live in fresh water and brackish water.
Adrianichthys roseni is a species of ricefish, a member of the family Adrianichthyidae which is endemic to Lake Poso on Sulawesi. Since the holotype was collected in 1978 there have been no reports of this species and if it still exists then it has a very low population. The IUCN categorise it as Critically Endangered. The specific name honours Donn E. Rosen (1929-1986) of the American Museum of Natural History.
