Natural range of the baiji

The baiji ( Cheenese : 白 ? 豚 ; pinyin : Aboot this soondbaijitun   ( help · info ) ) ( Lipotes vexillifer , Lipotes meanin "left behind", vexillifer "flag bearer") wis a freshwatter dowphin foond anly in the Yangtze River in Cheenae . Nicknamed "Goddess o the Yangtze" ( simplifeed Cheenese : ?江女神 ; traditeeonal Cheenese : 長江女神 ; pinyin : Chang Ji?ng n?shen ) in Cheenae, the dowphin is cried Cheenese river dowphin , Yangtze River dowphin , whitefin dowphin an Yangtze dowphin an aw. It is nae tae be confused wi the Cheenese white dowphin or the finless porpoise .

The baiji population declined drastically in decades as Cheenae industrialized an made hivy uise o the river for fishin, transportation, an hydroelectricity . Efforts wur made tae conserve the species, but a late 2006 expedeetion failed tae find ony baiji in the river. Organizers declared the baiji functionally extinct , [4] which wad mak it the first knt aquatic mammal species tae acome extinct syne the demise o the Japanese sea lion an the Caribbean monk seal in the 1950s. It wad be the first recordit extinction o a well-studied cetacean species (it is unclear if some previously extinct varieties wur species or subspecies) tae be directly attributable tae human influence an aw.

In August 2007, a Cheenese man reportitly videotaped a lairge white ainimal soummin in the Yangtze. [5] Altho it wis tentatively confirmed that the ainimal on the video is probably a baiji, [6] the presence o anly ane or a few ainimals, parteecularly o advanced age, is nae enough tae save a functionally extinct species frae true extinction. The last kent livin baiji wis Qi Qi (淇淇), who died in 2002.
