Devario Udenii
''Devario udenii'', is a fish belonging to the minnow family (Cyprinidae). It is endemic to Sri Lanka. However, the validity of the species description was noted problematic by several other local ichthyologists. Etymology The specific name ''udenii'', is in honor of Udeni Edirisinghe, an emeritus professor of University of Peradeniya for his contribution to the ichthyology and zoology in Sri Lanka. Description Body with 5–6 irregular vertical bars on anterior half. There are 14–17 pre-dorsal scales. Nuptial tubercles minute. Danionin notch present. Lateral line complete. There is a minute process on first infraorbital. Dorsum light yellowish with a bluish metallic sheen. Body silvery sheen laterally and ventrally. Vertical bars metallic blue with bright yellowish interspaces. Medial caudal rays dark blue. Other fins hyaline. Ecology It is found from fast flowing partially shaded waters of Homadola stream, a tributary of Gin Ganga The Gin Ganga ( si, ගිං ගඟ, ...

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthrop ...

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm 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 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 bony process of the skull. The pharyngeal teeth are unique to each species and are used ...

Gin Ganga
The Gin Ganga ( si, ගිං ගඟ, ''Gin River''), is a long river situated in Galle District of Sri Lanka. The river's headwaters are located in the Gongala Mountain range, near Deniyaya, bordering the Sinharaja Forest Reserve. The river flows past the villages of Baddegama, Nagoda, Thelikada and Hegoda. The Wakwella Bridge, which was the longest bridge in Sri Lanka, is built over this river. The river is also dammed at Thelikada. The mouth of the river is at Gintota, just north of Galle, where it flows into the Indian Ocean. See also * List of rivers in Sri Lanka The following table lists most rivers of Sri Lanka.

Freshwater Fish Of Sri Lanka
Sri Lanka is a tropical island situated close to the southern tip of India. It is situated in the middle of Indian Ocean. Because of being an island, Sri Lanka has many endemic freshwater fauna, including fish, crabs, molluscs, and other aquatic insects. Species List Class: Actinopterygii Freshwater fish are physiologically differ from marine and brackish water forms. The low salinity and high osmotic pressure makes them so different. Few fish can be found in all three ecological systems. There are 95 species of freshwater fish occur in the country, where 53 of those are endemic. 41% of all known species of fish of Sri Lanka are found in freshwater. There are about 70% of endemism of those fish. Most of them are listed into IUCN categories. Four ''Devario'' species were described in 2017 by Batuwita et al. However, the taxonomy and descriptions were cited as problematic by fellow local ichthyologists. Note: introduced species are not included in the list. Go to '' List of intr ...
