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.
This article is a list of biological species, subspecies, and evolutionary significant units that are known to have become extinct during the Holocene, the current geologic epoch, ordered by their known or approximate date of disappearance from oldest to most recent.
Caridina nilotica is a species of freshwater shrimp in the family Atyidae. It is native to Africa from the River Nile in Egypt to Lake Sibaya, South Africa, and is the only species of shrimp in Lake Victoria.
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 spinata, or yellow goldflake as it is commonly known in the aquarium hobby, is a freshwater shrimp from Sulawesi. It is endemic to Lake Towuti. It lives 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 loehae is a freshwater shrimp from Sulawesi. It is known as mini blue bee and orange delight shrimp in the aquarium trade. It is endemic to the Malili lake system. It lives on rocky substrates at a maximal depth of 5 metres.
Caridina fernandoi is a freshwater shrimp endemic to Sri Lanka, often found in lowland reservoir, slow flowing rivers and streams.
Caridina yunnanensis is a freshwater shrimp from Xundian and Songming Counties, Yunnan, China. It is known to live in mountain streams and reservoirs.
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 semiblepsia is a cave dwelling freshwater shrimp from China. It is only known from one location: the Baojing Cave in the provence of Hunan.
Caridina lanceolata is a freshwater shrimp from Sulawesi. It is widespread in the Malili lake system, including all three lakes. It can be found in pelagic swarms, as well as on a variety of substrates.
Caridina yilong is a species of freshwater shrimp in the family Atyidae. C. yilong was described from Lake Yilong in Yunnan, China, and was believed to be endemic to the margins of the lake among fringing vegetation. Only the type series has ever been collected, and the type locality of Lake Yilong has since dried up for extended periods of time due to the abstraction of water. Organic pollution caused by sedimentation along with agricultural and industrial pollution have caused this species to be assessed as Critically Endangered by the IUCN, with the caveat possibly extinct. In addition, two species of fish, Anabarilius macrolepis and Cyprinus yilongensis, that also were endemic to the lake are now extinct.
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.
