Adrianichthyidae
The ricefishes are a family (Adrianichthyidae) of small ray-finned fish that are found in fresh and brackish waters from India to Japan and out into the Malay Archipelago, most notably Sulawesi (where the Lake Poso and Lore Lindu species are known as buntingi). The common name ricefish derives from the fact that some species are found in rice paddies. This family consists of about 37 species in two genera (some recognize a third, '' Xenopoecilus''). Several species are rare and threatened, and some 2–4 may already be extinct. Description Most of these species are quite small, making them of interest for aquaria. ''Adrianichthys'' reach lengths of depending on the exact species involved, while the largest ''Oryzias'' reaches up to . Most ''Oryzias'' species are less than a half this length, with the smallest being up to only long. They have a number of distinctive features, including an unusual structure to the jaw, and the presence of an additional bone in the tail. ...

Oryzias Woworae
''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 (''O. latipes'') is commonly used in science as a model organism, while others have very small ranges and are threatened. They are small, up to long, and most are relatively plain in colour. The genus name ''Oryzias'' is a reference to the scientific name for rice, ''Oryza''. They have an unusual reproductive behavior where the female facultatively carries the eggs in a cluster at the pelvic or anal fins for a period after they have been fertilized. Species There are currently 33 recognized species in this genus: * '' Oryzias asinua'' Parenti, Hadiaty, Lumbantobing & Herder, 2013 * '' Oryzias bonneorum'' Parenti, 2008 * '' Oryzias carnaticus'' Jerdon, 1849 * '' Oryzias celebensis'' M.

Beloniformes
Beloniformes is an order composed of six families (and about 264 species) of freshwater and marine ray-finned fish: * Adrianichthyidae (ricefish and medakas) * Belonidae (needlefish) * Exocoetidae (flyingfishes) * Hemiramphidae (halfbeaks) * Scomberesocidae (sauries) * Zenarchopteridae (viviparous halfbeaks) With the exception of the Adrianichthyidae, these are streamlined, medium-sized fishes that live close to the surface of the water, feeding on algae, plankton, or smaller animals including other fishes. Most are marine, though a few needlefish and halfbeaks inhabit brackish and fresh waters. The order is sometimes divided up into two suborders, the Adrianichthyoidei and the Belonoidei, although this clade is referred to as Exocoetoidei in the 5th edition of ''Fishes of the World''. The Adrianichthyoidei contain only a single family, the Adrianichthyidae. Originally, the Adrianichthyidae were included in the Cyprinodontiformes and assumed to be closely related to the ...

Lake Poso
Lake Poso ( id, Danau Poso) is a lake in Central Sulawesi, Indonesia, and the third-deepest lake in Indonesia. The town of Pendolo is situated at the southern end of the lake, the town of Tentena is located at the northern end, while a number of smaller villages dot the shoreline. The lake drains into the Poso River at Tentena, which flows into the Molucca Sea at the town of Poso. Ecology The lake contains various fish, including the eel '' Anguilla marmorata'' which migrates between the lake and the sea, and 11 fish species that are endemic to the lake, notably buntingi ricefish ('' Adrianichthys'', '' Oryzias nebulosus'', '' O. nigrimas'' and '' O. orthognathus''), gobies ('' Mugilogobius amadi'' and '' M. sarasinorum''), and the halfbeak '' Nomorhamphus celebensis''. These endemics are all highly threatened; in some cases possibly already extinct. One of the reasons for the drastic decline of the native fish are introduced, non-native species, particularly Mozambique ti ...

Xenopoecilus
''Xenopoecilus'' is a genus of small fish in the family Adrianichthyidae. All members of the genus are threatened and endemic to lakes in Sulawesi, Indonesia. Pollution and the introduction of other fish into the lakes are the main reasons for the fall in ''Xenopoecilus'' numbers. Species Today many authorities do not recognize this genus, instead including the three species in other genera: * Egg-carrying buntingi (''Xenopoecilus oophorus'') – placed in genus ''Adrianichthys'' by FishBase. * Popta's buntingi (''Xenopoecilus poptae'') – placed in genus ''Adrianichthys'' by FishBase. * '' Xenopoecilus sarasinorum'' – placed in genus ''Oryzias ''Oryzias'' is a genus of ricefishes native to fresh and brackish water in east and south Asia.

Japanese Rice Fish
The Japanese rice fish (''Oryzias latipes''), also known as the medaka, is a member of genus ''Oryzias'' ( ricefish), the only genus in the subfamily Oryziinae. This small (up to about ) 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. Ecology Medaka live in small ponds, shallow rivers, and rice fields. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adrianichthys
''Adrianichthys'' is a genus of ricefishes. The genus is endemic to Lake Poso in Sulawesi, Indonesia. All four species are considered seriously threatened and two of these, ''A. kruyti'' and ''A. roseni'', have not been recorded for decades, leading to fears that they already are extinct.Parenti, L.R. (2011)Endemism and Conservation of the Native Freshwater Fish Fauna of Sulawesi, Indonesia Prosiding Seminar Nasional Ikan IV: 1-10. ''Adrianichthys'' are larger than the ''Oryzias'' ricefish, reaching lengths of depending on the exact species involved. The name of this genus is a compound ending in the Greek ''ichthys'' for "fish" with the first part honouring the linguist and missionary A missionary is a member of a religious group which is sent into an area in order to promote its faith or provide services to people, such as education, literacy, social justice, health care, and economic development.Thomas Hale 'On Being a Mi ...

Hyoid
The hyoid bone (lingual bone or tongue-bone) () is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies between the base of the mandible and the third cervical vertebra. Unlike other bones, the hyoid is only distantly articulated to other bones by muscles or ligaments. It is the only bone in the human body that is not connected to any other bones nearby. The hyoid is anchored by muscles from the anterior, posterior and inferior directions, and aids in tongue movement and swallowing. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. Its name is derived . Structure The hyoid bone is classed as an irregular bone and consists of a central part called the body, and two pairs of horns, the greater and lesser horns. Body The body of the hyoid bone is the central part of the hyoid bone. *At the front, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have taken ...

Cyprinodontiformes
Cyprinodontiformes is an order (biology), order of Actinopterygii, ray-finned fish, comprising mostly small, freshwater fish. Many popular aquarium fish, such as killifish and Poeciliidae, live-bearers, are included. They are closely related to the Atheriniformes and are occasionally included with them. A colloquial term for the order as a whole is toothcarps, though they are not actually close relatives of the true carps – the latter belong to the superorder Ostariophysi, while the toothcarps are Acanthopterygii. The families of Cyprinodontiformes can be informally divided into three groups based on reproductive strategy: Viviparity, viviparous and Ovoviviparity, ovoviviparous (all species give live birth), and Oviparity, oviparous (all species are egg-laying). The live-bearing groups differ in whether the young are carried to term within (ovoviviparous) or without (viviparous) an enclosing eggshell.

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "spac ...
