Cyprinus yilongensis

Cyprinus yilongensis (Common name: Yilong Lake Carp) is an extinct species of ray-finned fish in the family Cyprinidae. It was found only in Yilong Lake, Yunnan, China.^[2] It was last seen before 1981, when the lake was drained for 20 days, presumably causing the species' extermination.^[1]
