Cyprinus is the genus of typical carps in family Cyprinidae. Most species in the genus are of East Asia origin with only the common carp in Western Asia and Europe; this invasive species has also been introduced to many other regions around the world. Cyprinus are closely related to some more barb-like genera, such as Cyclocheilichthys and Barbonymus (tinfoils). The crucian carps (Carassius) of western Eurasia, which include the goldfish, are apparently not as closely related.
Dianchi Lake, also known as Lake Dian and Kunming Lake, is a large lake located on the Yunnan-Guizhou Plateau close to Kunming, Yunnan, China. Its nickname is the "Sparkling Pearl Embedded in a Highland" and it was the model for the Kunming Lake in the Summer Palace in Beijing. Its name is the source of Yunnan's Chinese abbreviation 滇.
Yilong Lake is a large freshwater lake located in Shiping County, Honghe Prefecture, Yunnan province, southwestern China. The lake has a surface area of approximately 32 square kilometres (12 sq mi) and is particularly notable for its scenery, including the colorful lotus flowers that bloom on its surface. It is located about 2 kilometres (1.2 mi) east of the county seat. The people who live in the vicinity of the lake are largely of the Yi ethnic group. As of the spring of 2013 a severe drought had resulted in substantial lowering of the water level.
Cyprinus yilongensis is an extinct species of ray-finned fish in the family Cyprinidae. It was found only in Yilong Lake, Yunnan, China. It was last seen before 1981, when the lake was drained for 20 days, presumably causing the species' extermination.
Fuxian Lake stretches out through Chengjiang, Jiangchuan and Huaning Counties in Yunnan Province, spanning an area of 212 square kilometers. The lake is ranked third-largest in Yunnan, after Dian Lake and Erhai Lake. Also the deepest lake in Yunnan, it is 155 meters deep at its greatest depth. It is also the third-deepest fresh water lake in China, after Tianchi and Kanas Lake.
Lake Barombi Mbo or Barombi-ma-Mbu is a lake near Kumba in the Southwest Region of Cameroon. It is located in the Cameroon volcanic chain, and is the largest volcanic lake in this region. It is one of the oldest radiocarbon-dated lakes in Africa, with the youngest lava flow in it being about one million years old. On old colonial maps the area was known as Elefanten Sea, but the elephants living in the area were extirpated due to ivory trading.
Anabarilius macrolepis is an extinct species of ray-finned fish in the family Cyprinidae that was endemic to Yilong Lake in Yunnan, China. It is believed that it became extinct when Yilong Lake dried up in 1981, as a result of water abstraction for agriculture. The species was not observed in 1983–84, and was declared extinct in 2011.
Cyprinus barbatus is a species of ray-finned fish in the genus Cyprinus. It is endemic to Lake Erhai in Dali, Yunnan, China. It is negatively impacted by agricultural and domestic pollution and introduced species. The IUCN considers it as critically endangered and possibly extinct, but records as recent as the 2000s (decade) show that it likely does survive.
Cyprinus yunnanensis is a critically endangered species of cyprinid fish in the genus Cyprinus from Qilu Lake in Yunnan, China. Despite surveys of the lake it has not been seen since the 1970s and it is possibly extinct. It reaches up to about 20 cm (8 in) in length.
Caridina dennerli is a small species of freshwater shrimp from Sulawesi (Indonesia) that grows up to 2.5 centimetres (1.0 in) in length. It takes its name from the German company Dennerle, which supported the expedition that led to the scientific description of the species. It is popularly known as the 'cardinal shrimp' in the aquarium trade.
Caridina woltereckae, or Sulawesi harlequin shrimp as it is commonly known in the aquarium hobby, is a freshwater shrimp from Sulawesi, Indonesia. It is endemic to Lake Towuti. It resembles the smaller and less contrastingly coloured Caridina spongicola, which is endemic to the same lake.
Caridina striata is a freshwater shrimp from Sulawesi. It is endemic to Lake Poso and Lake Towuti. Common names in the aquarium hobby are red line shrimp and red stripe shrimp. It is commonly found on rocky substrates.
Caridina ensifera is a freshwater shrimp from Sulawesi. It is one of the 11 species of Caridina endemic to Lake Poso. It lives on a variety of substrates, including wood, rocks, sand and macrophytes, but is also found in pelagic swarms. It is suspected to only live in shallow water.
Caridina caerulea is a freshwater shrimp from Sulawesi. It is one of 11 species in the genus Caridina that is endemic to Lake Poso. It lives on a variety of substrates, including wood, rocks, sand and macrophytes. It is suspected only to live in shallow water.
Caridina fernandoi is a freshwater shrimp endemic to Sri Lanka, often found in lowland reservoir, slow flowing rivers and streams.
Caridina masapi is a freshwater shrimp from Sulawesi. The species is endemic to the Malili lake system. It is commonly found on rocky substrate.
Caridina apodosis is a species of freshwater shrimp in the family Atyidae endemic to a mountain stream near the village of Tai Tong, China. Caridina apodosis is known from only the type series, collected in 1994. The exact type locality is unknown, and may be completely overtaken by urban sprawl. Caridina apodosis is assessed as Critically Endangered by the IUCN under criterion B1ab(iii)+2ab(iii) with the caveat 'possibly extinct'. C. apodosis is threatened by extensive water pollution as a result of urbanization, and the type locality may be unsuitable for inhabitance.
Caridina linduensis is a species of freshwater shrimp in the family Atyidae, endemic to Lake Lindu and its effluent stream in Sulawesi. It was known only from the type series, collected in 1904, and was recorded again in 2011 in a survey around Lake Lindu and is found in shallow littoral habitats of leaf litter, macrophytes, and dead wood. In the effluent stream it is found on soft substrates and slow flowing water, and is less common in the lake itself. The type locality of Lake Lindu was designated as a Recreation Park in 1978, and is part of the larger Lore Lindu National Park and UNESCO Biosphere Reserve. It is listed under IUCN criterion B1ab(iii,v) as Critically Endangered due to threats from introduced species of fish, land conversion to agriculture, logging, and shore disturbance caused by the grazing of water buffalo. Surveys are required to find the full distribution of C. linduensis, primarily its habitat in the effluent stream. C. linduensis is also sympatric with the recently described species Caridina dali and Caridina kaili.
