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 Endemism, 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 ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devario Malabaricus
The Malabar danio (''Devario malabaricus'') is a species of freshwater ray-finned fish belonging to the family Danionidae. Originating in Sri Lanka and the west coast of India, the fish has been circulated throughout the world through the aquarium fish trade. It grows to a maximum length of but rarely exceeds in a home aquarium. The Malabar danio is found in tropical climates in a wide variety of waters, from mountain streams to small pools, but it prefers flowing waters. It is an active, schooling fish that prefers to be in groups. Its diet consists of insects and plant matter. Malabar danios are oviparous, and spawn in shallow water after heavy rains among the plants growing on the bottom. An adult will spawn around 200 light-orange, sticky eggs that will hatch in one to two days. The fry will be free-swimming after the fifth day. The parents must be removed from aquaria to prevent them from eating the eggs. The species was earlier incorrectly considered a synonym of ' ...

Garra Ceylonensis
''Garra ceylonensis'' (the stone sucker or Ceylon logsucker) is a species of ray-finned fish in the cyprinid family. It is endemic to rivers and streams in Sri Lanka (formerly known as "Ceylon") - and is considered as a schooling fish. It is a rheophilic species and occurs in slow to moderately flowing rivers and streams, and ascends small, rocky streams in order to breed. It primarily feeds on aufwuchs - algae and diatoms. Taxonomy A 2021 study found ''G. ceylonensis'' to be a sister species to the mullya garra (''Garra mullya'') from mainland India, which itself may comprise two species. ''G. ceylonensis'' comprises primarily six genetically distinct subclades that are each tied to a single river basin, albeit with two exceptions. Evolution The ancestor of ''G. ceylonensis'' colonized Sri Lanka from India once during the late Pliocene, via a former isthmus that existed in the Palk Strait, and from the Pleistocene until its submergence, the still-exposed isthmus may have ...

Esomus Danricus
The Indian flying barb (''Esomus danrica''), historically flying barb, is one of the species known in the group flying barbs owing to their extremely long barbels.
