Danionella Translucida Bolton Aquarium
''Danionella'' is a genus of danionin fish found in freshwater habitats in Myanmar and West Bengal, India. It includes some of the List of smallest fish in the world, smallest fishes. Distribution Four out of five described species of ''Danionella'' are found in Myanmar. ''D. translucida'' is described from the Irrawaddy River, Ayeyarwady River basin, and ''D. mirifica'' was described from the Kamaing area in upper Myanmar. ''Danionella priapus'' is Endemism, endemic to India. Description When first described, ''Danionella translucida'' was the smallest Ostariophysi, ostariophysan and the smallest adult vertebrate to inhabit fresh water. Its adult size ranges from 10–12 millimetres (.43–.47 in) fish measurement, 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 scale (zoology), scales and barbel (anatomy), barbels, but possess a lateral line. ''D. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Scale (zoology)
In zoology, a scale (; ) is a small rigid plate (animal anatomy), plate made out of keratin that grows out of Vertebrate animals' skin to provide protection. In lepidopterans (butterflies and moths), scales are plates on the surface of the insect wing, made out of chitin instead of keratin, and provide coloration. Scales are quite common and have evolved multiple times through convergent evolution, with varying structure and function. Scales are generally classified as part of an organism's integumentary system. There are various types of scales according to the shape and class (biology), class of an animal. Fish scales Fish scales are skin, dermally derived, specifically in the mesoderm. This fact distinguishes them from reptile scales paleontologically. Genetically, the same genes involved in tooth and hair development in mammals are also involved in scale development.

Danionella Translucida
''Danionella translucida'' is an extremely small (1.1 cm long) species of freshwater ray-finned fish belonging to the family Danionidae. This fish is 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. Mammals and birds, in contrast ...s. There are no melanophores on the dorsal surface except on the head over the posterior part of the brain. On the posteri ...

Danionella Dracula
The dracula fish (''Danionella dracula'') is a species of freshwater ray-finned fish belonging to the family Danionidae. 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. 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 structure is cartilaginous: it has 44 fewer bones than the zebrafish, and thus it is ...

Danionella Cerebrum (cropped)
''Danionella cerebrum'' is a species of freshwater ray-finned fish belonging to the family Danionidae. This fish was reported in 2021 from turbid low altitude streams on the southern and eastern slopes of the Bago Yoma mountain range in Myanmar as well as from an irrigation canal southwest of the town of Hmawbi in Yangon Division. 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 exhibit 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 persists into adulthood, ''Danionel ...

Danio Rerio
The zebrafish (''Danio rerio'') is a species of freshwater ray-finned fish belonging to the family Danionidae of the order Cypriniformes. Native to South Asia, it is a popular aquarium fish, frequently sold under the trade name zebra danio (and thus often called a " tropical fish" although it is both tropical and subtropical). The zebrafish is an important and widely used vertebrate model organism in scientific research, particularly developmental biology, but also gene function, oncology, teratology, and drug development, in particular pre-clinical development. It is also notable for its regenerative abilities, and has been modified by researchers to produce many transgenic strains. Taxonomy The zebrafish is a derived member of the genus '' Brachydanio'', of the family Cyprinidae. It has a sister-group relationship with '' Danio aesculapii''. Zebrafish are also closely related to the genus '' Devario'', as demonstrated by a phylogenetic tree of close species. Distr ...
