Danionella
''Danionella'' is a genus of danionin fish found in freshwater habitats in Myanmar and West Bengal, India. It includes some of the smallest fishes. Distribution Four out of Five Described species of ''Danionella'' are found in Myanmar. ''D. translucida'' is described from the Ayeyarwady River basin, and ''D. mirifica'' was described from the Kaiming area in upper Myanmar. Danionella priapus can only be found in India. Description When first described, ''Danionella translucida'' was the smallest ostariophysan and the smallest adult vertebrate to inhabit fresh water. Its adult size ranges from 10–12 millimetres (.43–.47 in) SL. ''D. mirifica'' gets slightly larger, at about 14 mm (.55 in) SL, but is still one of the smallest freshwater fishes. ''Danionella'' species lack scales and barbels, but possess a lateral line. ''D. mirifica'' has a single row of melanophores between the pelvic fins and the tips of the cleithra, and there is a lack of ...

Danionella Cerebrum
''Danionella cerebrum'' is a cyprinid fish species reported in 2021 from turbid low altitude streams on the southern and eastern slopes of the Bago Yoma mountain range in Myanmar. It was previously erroneously identified as '' Danionella translucida'' due to the close resemblance and similar geographical distribution of the two species. Adult fish of the species measure only 10-13.5 mm in size and have a brain volume of just 0.6 mm3 which is thus far the smallest known adult vertebrate brain. ''Danionella cerebrum'' larvae have been shown to exihibit similarities but also differences in their locomotor activity compared to the zebrafish (Danio rerio) to which they are evolutionary closely related. Due to its miniature size, rich behavioural repertoire, and optical translucency that persits into adulthood, ''Danionella cerebrum'' holds great promise for non-invasive whole-brain in vivo imaging analyses with single cell resolution in an adult vertebrate and is beginning to emer ...

Danionella Priapus
''Danionella priapus'' is a species of ''Danionella'' endemic to India. It is sexually dimorphic and, like other species in the genus, possesses a skeleton with fewer bones than the closely related zebrafish. However, it has a number of distinguishing features which differentiate it from others in the genus, with the most notable example being the conically projecting genital papilla between the funnel-shaped pelvic fins of males.Britz, Ralf. “''Danionella Priapus'', a New Species of Miniature Cyprinid Fish from West Bengal, India (Teleostei: Cypriniformes: Cyprinidae).” ''Zootaxa'', vol. 2277, no. 2277, Magnolia Press, 2009, pp. 53–60, https://doi.org/10.11646/zootaxa.2277.1.4.

Danionella Translucida
''Danionella translucida'' is an extremely small (1.1 cm long) species of cyprinid fish endemic to Myanmar. When described, it was considered to be one of the smallest fish. It was collected from the roots of floating aquatic plants in a slow-flowing, shallow stream (maximum depth 1 m) in the Pegu Division of Myanmar. It was found alongside ''Danio'', '' Microrasbora'', '' Erethistes'', and ''Oryzias'' species. Observed in life, ''D. translucida'' is almost perfectly transparent except for its eyes. It has a distinctive pattern of melanophore Chromatophores are cells that produce color, of which many types are pigment-containing cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods.

Danionin
The danionins are a group of small, minnow-type fish belonging to the family Cyprinidae. Members of this group are mostly in the genera ''Danio'', '' Devario'', and ''Rasbora''. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. ''Danio'' species tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. ''Devario'' species tend to have vertical or horizontal bars, and short, rudimentary barbels, if present at all. All danionins are egg scatterers, and breed in the rainy season in the wild. They are carnivores, living on insects and small crustaceans. Taxonomy The grouping of fish now deemed danionins has been the subject of constant research and speculation throughout the 20th century. Nearly all the fish classed within the genera ''Danio'' and ''Devario'' were originally placed in the genus ''Danio'' upon dis ...

Danionella Dracula
The dracula fish (''Danionella dracula'') is a species of tropical danionin fish from the cyprinid family. It is a freshwater fish endemic to Myanmar. A close relative is ''Danio rerio'', the zebrafish of aquariums. It is named dracula after its unusual "fangs"; male dracula fish have protruding tooth-like bones stemming from their jawbones. Males have been observed using their fangs to spar with other males.Black, Richard (2009-03-11)'Dracula' fish shows baby teeth BBC News. Retrieved on 2009-03-11. Identified in April 2007 from specimens shipped to the United Kingdom in a consignment of aquarium fishes, the dracula fish has so far only been found in the wild in a small stream at Sha Du Zup between Mogaung and Tanai in northern Myanmar. It is a colourless miniature species and grows to a maximum size of around . The fish has an elongate body with a large head and eyes. Dracula fish lack scales and the upper body is dominated by the jaws on large males. Much of the fish's structu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ostariophysi
Ostariophysi is the second-largest superorder of fish. Members of this superorder are called ostariophysians. This diverse group contains 10,758 species, about 28% of known fish species in the world and 68% of freshwater species, and are present on all continents except Antarctica. They have a number of common characteristics such as an alarm substance and a Weberian apparatus. Members of this group include fish important to people for food, sport, the aquarium industry, and research. Taxonomy The superorder is divided into two series, Anotophysi and Otophysi. However, in older literature, Ostariophysi was restricted only to the fish that are currently classified under Otophysi. Otophysi was coined in 1970 by Rosen and Greenwood to separate the traditional Ostariophysians from the added Gonorynchiformes. The superorder is classified below: *Series Anotophysi ** Gonorynchiformes, about 37 species *Series Otophysi (Euostariophysi) ** Cypriniformes (minnows and allies), about ...

Barbel (anatomy)
In fish anatomy and turtle anatomy, a barbel is a slender, whiskerlike sensory organ near the mouth. Fish that have barbels include the catfish, the carp, the goatfish, the hagfish, the sturgeon, the zebrafish, the black dragonfish and some species of shark such as the sawshark. Barbels house the taste buds of such fish and are used to search for food Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ... in murky water. The word "barbel" comes from the Middle Latin ''barbula'', for "little beard." Barbels are sometimes erroneously referred to as '' barbs'', which are found in bird feathers for flight. Barbels may be located in a variety of locations on the head of a fish. "Maxillary barbels" refers to barbels on either side of the mouth. Barbels may also be nasal, exten ...
