Betta Raja
''Betta raja'' is a species of betta endemic to the island of Sumatra in Indonesia. It is an inhabitant of swamps in lowland forests. This species grows to a length of SL. It is used as bait by local fishermen and has also been found in the aquarium trade. Despite its scientific epithet ''"raja"'' meaning "Prince" or "king", this species is not identical to the aquarium breed - the King betta. The derivation of the King betta is not fully known and may or may not involve crossbreeding with ''B. raja''.Juniper Russo (2009):"King Betta" Variety Sold at Petco References raja ''Raja'' (; from , IAST ') is a royal title used for South Asian monarchs.

King Betta
The King betta is a popular aquarium fish of unknown provenance. Description The King betta generally grows to about 5–6 cm (2–2 1/2 in). Its pigments are generally vibrant beige to a white. As with most bettas, King betta females are smaller and less colorful than the males. The life span of the King betta is short, generally 2–3 years, rarely reaching four. The King betta is (as are all other bettas) members of the gourami family ( Osphronemidae) and prefers a temperature of 78–82 °F. History Hardly anything is known about the King betta. Some people say that ''Betta raja'' and ''Betta splendens'' cross bred in nature to create the King betta we know today. Others suppose that the King betta was bred from wild stock of ''B. raja''. Diet King bettas eat fish flakes, pellets, bloodworms and freeze-dried brine shrimp. Behavior Male and female king bettas flare or puff out their gills in order to appear more impressive, either to intimidate rivals or attra ...

Tan Heok Hui
Heok Hui Tan is a Singaporean ichthyologist at the Lee Kong Chian Natural History Museum of the National University of Singapore. Dr. Tan's main interest lies in the systematics of Southeast Asian freshwater fishes, encompassing taxonomy, ecology and biogeography. His primary areas of research focus on neglected and de novo habitats such as peat swamp forests Peat swamp forests are tropical moist forests where waterlogged soil prevents dead leaves and wood from fully decomposing. Over time, this creates a thick layer of acidic peat. Large areas of these forests are being logged at high rates. Peat ..., swamp forests, and rapids. As of 2018, Tan has authored two species of Osphronemidae ( Luciocephalus aura and Betta pi).

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...
