Lake Malawi, also known as Lake Nyasa in Tanzania and Lago Niassa in Mozambique, is an African Great Lake and the southernmost lake in the East African Rift system, located between Malawi, Mozambique and Tanzania.
Lake Victoria is one of the African Great Lakes. With a surface area of approximately 59,947 km2 (23,146 sq mi), Lake Victoria is Africa's largest lake by area, the world's largest tropical lake, and the world's second-largest fresh water lake by surface area after Lake Superior in North America. In terms of volume, Lake Victoria is the world's ninth-largest continental lake, containing about 2,424 km3 (1.965×109 acre⋅ft) of water. Lake Victoria occupies a shallow depression in Africa. The lake has an average depth of 40 m (130 ft) and a maximum depth of 80–81 m (262–266 ft). Its catchment area covers 169,858 km2 (65,583 sq mi). The lake has a shoreline of 7,142 km (4,438 mi) when digitized at the 1:25,000 level, with islands constituting 3.7% of this length.
Lake Tanganyika is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo, Burundi, and Zambia—with Tanzania (46%) and the DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean.
The Western Ghats, also known as the Sahyadris, is a mountain range that stretches 1,600 km (990 mi) along the western coast of the Indian peninsula. Covering an area of 160,000 km2 (62,000 sq mi), it traverses the states of Gujarat, Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu. The mountains form an almost continuous chain of mountains along the western edge of the Deccan Plateau from the Tapti river to the southern tip of the Indian peninsula at Kanniyakumari. The Western Ghats meets with the Eastern Ghats at Nilgiris before continuing south.
Stenodus leucichthys is a species of freshwater whitefish in the family Salmonidae. In the strict sense its natural distribution is restricted to the Caspian Sea basin. It is now considered extinct in the wild, but survives in cultured stocks. The nelma, a more widespread species of Eurasian and North America, is sometimes considered its subspecies.
River stingrays or freshwater stingrays are Neotropical freshwater fishes of the family Potamotrygonidae in the order Myliobatiformes, one of the four orders of batoids, cartilaginous fishes related to sharks. They are found in rivers in tropical and subtropical South America. A single marine genus, Styracura, of the tropical West Atlantic and East Pacific are also part of Potamotrygonidae. They are generally brownish, greyish or black, often with a mottled, speckled or spotted pattern, have disc widths ranging from 31 to 200 centimetres (1.0–6.6 ft) and venomous tail stingers. River stingrays feed on a wide range of smaller animals and the females give birth to live young. There are more than 35 species in five genera.
The European river lamprey, also known as the river lamprey or lampern, is a species of freshwater lamprey.
The New Zealand longfin eel, also known as ōrea, is a species of freshwater eel that is endemic to New Zealand. It is the largest freshwater eel in New Zealand and the only endemic species – the other eels found in New Zealand are the native shortfin eel, also found in Australia, and the naturally introduced Australian longfin eel. Longfin eels are long-lived, migrating to the Pacific Ocean near Tonga to breed at the end of their lives. They are good climbers as juveniles and so are found in streams and lakes a long way inland. An important traditional food source for Māori, who name them ōrea, longfin eel numbers are declining and they are classified as endangered, but over one hundred tonnes are still commercially fished each year.
The Indo-Pacific tarpon, also known as the oxeye herring or simply herring due to its superficial resemblance to the true herrings, of which it is not a member, is the smaller of the two species of tarpon and lives in Indo-Pacific waters.
The largetooth sawfish is a species of sawfish in the family Pristidae. It is found worldwide in tropical and subtropical coastal regions, but also enters freshwater. It has declined drastically and is now critically endangered.
The Northern straight-mouth nase is a species of ray-finned fish in the family Cyprinidae. It is found in Portugal and Spain. Its natural habitat is rivers. It is threatened by habitat loss.
The Iberian nase is a species of freshwater fish in the family Cyprinidae. It is found in Portugal and in Spain. Its natural habitats are rivers and intermittent rivers.
The humpback whitefish, also referred to as the bottom whitefish, the Arctic whitefish or the pidschian, is a species of freshwater whitefish with a northern distribution. It is one of the members in the broader common whitefish complex, or the Coregonus clupeaformis complex. This fish lives in estuaries and brackish water near river mouths, in deltas and in slowly running rivers, in large lakes with tributaries, and floodplain lakes. It can migrate long distances upriver for spawning.
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish, and hypogean fish.
The wildlife of Pakistan comprises a diverse flora and fauna in a wide range of habitats from sea level to high elevation areas in the mountains, including 195 mammal, 668 bird species and more than 5000 species of Invertebrates. This diverse composition of the country's fauna is associated with its location in the transitional zone between two major zoogeographical regions, the Palearctic, and the Oriental. The northern regions of Pakistan, which include Khyber Pakhtunkhwa and Gilgit Baltistan include portions of two biodiversity hotspot, Mountains of Central Asia and Himalayas.
Stenodus nelma, known alternatively as the nelma, sheefish, siifish, inconnu or connie, is a commercial species of freshwater whitefish in the family Salmonidae. It is widespread in the Arctic rivers from the Kola Peninsula eastward across Siberia to the Anadyr River and also in the North American basins of the Yukon River and Mackenzie River.
Achondrostoma is a genus of freshwater fish in the family Cyprinidae, the carps and minnows. It is endemic to the Iberian Peninsula.
Achondrostoma occidentale is a species of freshwater fish in the family Cyprinidae. This fish is from Portugal.
Achondrostoma oligolepis is a species of cyprinid fish. It is endemic to central and northern Portugal and known from between Limia and Tornada drainages, south of Douro. It occurs in the lower stretches of rivers and streams. It can grow to 25 cm (9.8 in) total length, although it typically measures about 15 cm (5.9 in) TL.
Achondrostoma salmantinum is a species of freshwater fish in the family Cyprinidae. It is native to five tributaries in the Duero basin in the Province of Salamanca, Spain. It is normally found in clear, seasonal streams with sandy substrates, preferring the slower flowing stretches which have an abundant vegetation of aquatic macrophytes. The species is common within its restricted range but it has a declining population and it is threatened mainly by falling water tables caused by the abstraction of water for agriculture and the construction if dams and weirs.
