The Baiji was a freshwater dolphin found only in the Yangtze River in China. Nicknamed "Goddess of the Yangtze" in China, the dolphin was also called Chinese River Dolphin, Yangtze River Dolphin, Whitefin Dolphin and Yangtze Dolphin. It is not to be confused with the Chinese White Dolphin.
The Xinhua News Agency announced on 4 December 2006 that no Chinese River Dolphins were detected in a six-week survey of the Yangtze River conducted by 30 researchers. The failure of the Yangtze Freshwater Dolphin Expedition raised suspicions of the first unequivocal extinction of a cetacean species due to human action. Poor water and weather conditions may have prevented sightings, but expedition leaders declared it "functionally extinct" on 13 December 2006 as fewer are likely to be alive than are needed to propagate the species.
