🐋Baiji
Asiatisk floddelfin (Lipotes vexillifer), ibland kallad Changjiangdelfin, Yangtzedelfin eller, med det vanligaste kinesiska namnet, Baijidelfin (白鱀豚), är en art i underordningen tandvalar. Arten antas vara utdöd, eller mycket nära utrotning. En expedition i december 2006 kunde inte finna några individer. Asiatisk floddelfin förekommer eller förekom uteslutande i den kinesiska floden Yangtze, inklusive mindre angränsande vattendrag och tillhörande insjöar.
