Haditha Cavefish (Caecocypris basimi)
The Haditha Cavefish was described in 1980 based on material that was collected in 1977 from aquifers, underground layers of water-bearing rocks, near the city of Haditha, Iraq.
The groundwater level has drastically lowered since than due to water extraction; the species hasn’t been found since 1983, despite comprehensive surveys and appears to be extinct now.
