Yangtze Giant Softshell Turtle (image) Wildlife Conservation Society Share Print E-Mail Caption One of the last of its kind: a Yangtze giant softshell turtle (Rafetus swinhoei) surfaces in a lake in Vietnam. Once occurring in the river basins of China and Vietnam, the turtle (which can weigh up to 250 pounds) has been decimated as a result of wetland destruction, and water pollution, and poaching. Only four individuals are known to exist. Credit Brian D. Horne/Wildlife Conservation Society Usage Restrictions One-time usage only. Use photo credit.
