Balantiocheilos
''Balantiocheilos'' is a small genus of cyprinid fish from southeast Asia. It includes two species. Species *'' Balantiocheilos ambusticauda'' H. H. Ng & Kottelat, 2007 (Burnt tail fish) *'' Balantiocheilos melanopterus'' ( Bleeker, 1851) (Tricolor sharkminnow) Distribution The range of ''B. ambusticauda'' is listed as including the Chao Phraya and Mae Klong drainages in Thailand; the original distribution of this species included the Chao Phraya River drainage from Bangkok upriver to the lower Nan River. It has also been reported in the Mekong Basin in Vietnam, Cambodia and Laos from the Tonlé Sap lake to the lower Nam Ngum River, but confirmed records from this basin are lacking and this is not recognized as part of its range by the IUCN. Previous records of ''B. melanopterus'' from the same rivers is due to confusion with ''B. ambusticauda''; ''B. melanopterus'' only occurs in the Malay Peninsula, Sumatra, and Borneo. Large numbers of ''B. melanopterus'' are exported fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bala Shark
The bala shark (''Balantiocheilos melanopterus''), also known as the tricolor shark, tricolor sharkminnow, silver shark, or shark minnow, is a fish of the family Cyprinidae, and is one of the two species in the genus ''Balantiocheilos''. This species is not a true shark, but is commonly so called because of its torpedo-shaped body and large fins. Distribution The bala shark occurs in the Malay Peninsula, Sumatra, and Borneo. Previous records further north in the Mekong and Chao Phraya River is due to confusion with the recently described and possibly extinct '' B. ambusticauda'' (although the presence of any ''Balantiocheilos'' in the Mekong is questionable). Appearance and anatomy These fish have a silver body with black margins on their dorsal, caudal, anal, and pelvic fins. They have big eyes to find and catch their prey. The bala shark will grow to a maximum length of . Habitat and ecology Bala sharks are found in midwater depths in large and medium-sized rivers and lakes. ...

Burnt-tailed Barb
The burnt-tailed barb (''Balantiocheilos ambusticauda''), also known as Siamese bala-shark, is a possibly extinct freshwater fish species from the family Cyprinidae. It is or was endemic to the Mae Klong and Chao Phraya River basins in Thailand. Taxonomy and discovery The burnt-tailed barb was long considered as conspecific with the bala shark (''Balantiocheilos melanopterus'') until it was described as separate species in 2007.Ng, Heok Hee; Kottelat, Maurice (2007). "''Balantiocheilos ambusticauda'', a new and possibly extinct species of cyprinid fish from Indochina (Cypriniformes: Cyprinidae)". Zootaxa 1463: 13–20. The holotype was collected by German ichthyologist Rolf Geisler (1925–2012) in February 1967 at Bung Boraphet, Nakhon Sawan province, Thailand. The material labelled as paratypes was collected by Rodolphe Meyer de Schauensee in 1936, by M. Harmand in 1883, and by Marie Firmin Bocourt in 1862. Description The burnt-tailed barb is closely related to the bala sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chao Phraya
The Chao Phraya River is the major river in Thailand, with its low alluvial plain forming the centre of the country. It flows through Bangkok and then into the Gulf of Thailand.

It is unknown what name, if any at all, was used for the river in older times. The river was likely known simply by the Thai word for 'river', (), and foreign documents and maps, especially by Europeans visiting during the Ayutthaya period, usually named the river the ''Menam''. The name Chao Phraya likely comes from (), an alternative name, documented from around 1660 in the reign of King Narai, of the settlement that is now Samut Prakan. Historian Praphat Chuvichean suggests that the name, which is a title of nobility, originated from the story of two Khmer idols being unearthed in 1498 at the settlement that was by the mouth of the river at the tim ...

Cyprinidae is a Family (biology), family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barb (fish), barbs and barbel (fish), barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate, vertebrate animal family overall, with about 1,780 species divided into 166 valid genus, genera. Cyprinids range from about in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless, or ''agastric'', fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a Process (anatomy), bony process of the skull. The ...
