The now-confirmed specimen increases the global population of the world's rarest turtle, and unarguably one of the Earth's rarest animals, to four.

After several years of relentless search by our partners at the Asian Turtle Program, a photograph was captured by Nguyen Van Trong of a large softshell turtle residing in the lake in May 2017. The photograph however was not enough to confirm the specimen as Rafetus swinhoei. In 2017, the Turtle Survival Alliance partnered with the Asian Turtle Program and Washington State University to intensify the effort to confirm the existence of R. swinhoei in Xuan Khanh Lake through the use of environmental DNA (eDNA). The efforts paid off when Dr. Caren Goldberg of the Washington State University confirmed a clear positive result for R. swinhoei DNA, based upon her analysis of eDNA samples from Xuan Khanh Lake. Although the effort to capture this specimen and bring it together with the other last remaining animals will be immense, the confirmation of its existence significantly increases the chance of survival for the species. Of the three previously known specimens, only one other R. swinhoei is known to live in the wild, in Dong Mo Lake, Vietnam, while the other two specimens, a pair, reside at the Suzhou Zoo, Suzhou China.

The Biodiversity Conservation Agency (BCA) of the Ministry of Natural Resources and the Environment (MoNRE) and the Fisheries Department and Forest Protection Department (FPD) of Vietnam have both supported surveys and conservation efforts for R. swinhoei. The analysis of the eDNA was made possible by support from several institutions including the Cleveland Metroparks Zoo, Turtle Conservation Fund, International Union for the Conservation of Nature (IUCN), Critical Ecosystem Partnership Fund, and British Chelonia Group, as well as numerous private donors.

Their survival also needs YOU. We ask that you please DONATE TODAY to aid in the efforts to preserve the world's rarest turtle, Rafetus swinhoei.
