Caecocypris

The species is classed as Critically endangered, possibly extinct, by the IUCN, as there have been no records since 1983 despite a comprehensive survey in 2012.

[1] The primary threat is water extraction, which has lowered the groundwater level.

[1] It is placed as one of the top 10 lost freshwater fishes to be found.

[4] The cavefish Garra widdowsoni is found in the same place and it has also drastically declined, but it is not as rare as Caecocypris basimi.

[6] The holotype of Caecocypris basimi, collected by Dr. Basim M Al Azzawi in 1977, is deposited at the British Museum of Natural History and other specimens are at the Australian Museum.
