The baiji (Cheenese: 白鱀豚; pinyin: 
báijìtún ) (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: 长江女神; traditeeonal Cheenese: 長江女神; pinyin: Cháng Jiāng nǚshén) in Cheenae, the dowphin is an aa cried Cheenese river dowphin, Yangtze River dowphin, whitefin dowphin an Yangtze dowphin. 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 an aa 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.
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.

La baijii (Latina linguo: Lipotes vexillifer) esas delfino fluviala qua nur habitis la Chiniana fluvio Yangce. Altra nomi por tadentizita cetaceo esas: beiji, pai-chi, delfino de blanka floso, delfino di la fluvio Yangce, mem en Chinia onu nomizas olu Deino di la Yangce (長江 女神). Desfortunoze ta deino ne esas nemortiva, fakte grupo de ciencisti exploris ye 2006 la fluvio Yangce dum plura semani e trovis nula delfino. La Deino di la Yangce esas speco fakte extingita.
Le “baiji” esas delfini fluviala di qua maxima longitudo esas 2.5 metri e pezo cirkum duacent kilogrami. La quar yari evanta delfinuli e la sis yari evanta delfinini esas sexuale matura. En singla duesma yaro naskas delfino qua alaktesas da lua matro dum un yaro. La baijii povas vivar cirkum 24 yari.
Malgre ke ta delfini povis natar kun granda rapideso (60 km/h) li preferis natar plu lente, kun rapideso de 10-15 kilometri hore. Dum lenta natado li povis uzar lia povoza “sonaro” por trovar fishi quin li kaptis e devoris da ta blanka cetaceo fluviala. En la ne-diafana aquo di la Yangce la okuli ne esas tre utila, yen pro quo olti di la baijii esis mikra.
Segun la trovita fosili ta delfini habitis la oceano Pacifiko ma ekmigris olu e habiteskis la fluvio Yangce ye duadek milion yari ante nun. La Yangce esas fluvio tre granda, ma irgakaze ne enorma, do la nombro de delfini nulatempe esis tro granda ma suficanta por la existo de ta speco dum milioni di yari. Dum la ero Han la nombro de ta cetacei esis adminime kinamil, segun esas lektebla en la libro Erya.
Recente Chinia rikonocis la extingo-risko de la fluvio-delfino. En 1978 la Akademio China pri Cienco fondis la Inquesteyo pri la Fluviala Delfino, dependanta de la Instituto Wuhan pri Hidrobiologio. Irgakaze la laboro da ta Instituto nulatempe esis intensa nek efikiva. La unesma organizuro qua protekteskis la baijio esis la Fonduro “Delfino Baijio”, di Wuhan. Ta organizuro naskis en 1996, e kolektis cirkum 100000 dolar qui uzesis por konservar celuli “in vitro” di la delfino di la Yangce e por sustenar la delfineyo di Shishou olqua regretinde inundesis en 1998. Douglas Adams e Mark Carwardine fotografis e video-registragis baijii por la BBC. Lia registraguri spektigesis televizionale kun la titulo “Lastafoye videbla” (Last Chance to See). Libro samtitulizita publikigesis en 1990, en ta libro esis fotografuri di delfinulo kaptita, nomizita Qi Qi, qua vivis en la delfineyo di la Instituto de Hidrobiologio di Wuhan de 1980 til la 14ma di julio 2002. Ta delfino deskovresis da peskisto en la lako Dongting, ed olu esis la unika delfino habitanta la delfineyo. Altra baijio kaptita en 1996 mortis en 1997 en la Rezerveyo Mi-naturala di Shishou Tian-e-Zhou. Delfinino trovesis en la insulo Chongming, proxim Shangai en 1998, ma dum lua kaptiveso, duranta un monato, ta baijio refuzis omna nutrivi e fine mortis pro hungro.
La baijio observesis lastafoye ye septembro 2004. Ye la 4ma di decembro 2006 la novaji-agenterio Xinhua dissavigis ke dum detaloza serchado durinta sis semani da grupo de triadek ciencisti, mem kun sono-detektili submersebla, nula baijio trovesis en la fluvio Yangce. Certe ankore povas existar ula baijii vivanta qui ne observesis da la ciencisti, ma mem le maxim optimista opinionas ke la nombro de delfini vivanta ne esus irgakaze suficanta por evitar la extingo. La delfino fluviala di la Yangce, la deino di la fluvio, la baijio, deklaresis oficale “speco extingita”.
Ne esas unika ma plura kauzi qui extingis ta anciena speco. Sendube la nelegala chaso, qua sempre existis, esas kulpanta, ma anke la pesko ecesanta, la dogi, la kontaminita aquo di la fluvio e la shoki kontre motorizita navi.
La ciencisti intencis kaptar la vivanta baijii e transpozar oli en proxima lago por salvar ta cetaceo, ma ta intenco arivis kun tardeso, desfortunoze ne pluse existas vivanta beijii, la deino di la fluvio Yangce nur existas en la memoro.
