Lipotes vexillifer (Yangtze River Dolphin; White-flag Dolphin; Baiji; Chinese river dolphin)
The baiji (Chinese: 白鱀豚; pinyin: About this sound báijìtún , Lipotes vexillifer, Lipotes meaning "left behind", vexillifer "flag bearer") is a freshwater dolphin found only in the Yangtze River in China. Nicknamed "Goddess of the Yangtze" (simplified Chinese: 长江女神; traditional Chinese: 長江女神; pinyin: Cháng Jiāng nǚshén) in China, the dolphin is also called Chinese river dolphin, Yangtze River dolphin, whitefin dolphin and Yangtze dolphin.
According to Chinese legend, this graceful freshwater dolphin is the reincarnation of a drowned princess. It has been declared a national treasure of the highest order, but the Yangtze River is today one of the worlds busiest and most degraded waterways, and for over two decades conservationists have recommended that the species can only be protected by establishing an ex situ breeding population in an oxbow lake away from the main Yangtze channel. However, despite extensive debate by international conservation organisations, little active work has ever been carried out to protect the rapidly declining population. A recent range-wide survey was unable to find any surviving baiji left in the river, and the species in now probably extinct.
