paragraph_text: Yangtze giant softshell turtle
  
  The Yangtze giant softshell turtle (Rafetus swinhoei) is a softshell turtle endemic to China and Vietnam and is possibly the largest living freshwater turtle. Due to various factors such as habitat loss, wildlife trafficking, trophy hunting, and the Vietnam War, the species population has been reduced to only three male individuals, rendering it functionally extinct similar to the northern white rhinoceros and ivory-billed woodpecker. There is one captive individual in Suzhou Zoo in China, and two wild individuals at Dong Mo Lake in Vietnam. Efforts to save the species from extinction through various means of assisted reproduction in captivity have been ongoing since 2009 by the Suzhou Zoo and Turtle Survival Alliance.
  
  Despite efforts to breed the turtles naturally, the eggs laid by the final known female were all infertile and unviable. In May 2015, artificial insemination was performed for the first time in the species. In July of the same year, the female laid 89 eggs, but like all previous natural attempts, they were all unviable. In April 2019, the female individual at the zoo died after another failed artificial insemination attempt. In 2020, a female was discovered in the wild, reigniting hope for the survival of the species. However, this individual was found dead in early 2023. Several searches across China and Vietnam are currently underway to locate female individuals to breed with the final known males, or to undergo artificial insemination.
