  1. The baiji: Why this extinct river dolphin still matters

  2. People also ask
    Lipotes vexillifer, also known by the common name baiji, is found in China in the mouth of the Chang Jiang (Yangtze) to a point about 1900 km up the river, as well as in the middle and lower regions of the Quintangjiang River and in the Dongting and Poyang lakes. ( Nowak, 1999)
    The baiji ( Chinese: 白鱀豚; pinyin: báijìtún; IPA: [pǎɪtɕîtʰwə̌n] ⓘ; Lipotes vexillifer, Lipotes meaning "left behind" and vexillifer "flag bearer") is a possibly extinct species of freshwater dolphin native to the Yangtze river system in China. It is thought to be the first dolphin species driven to extinction due to the impact of humans.
    The only fossil placed close to L. vexillifer is Prolipotes yujiangensis ( Zhou et al., 1984 ), roughly of Miocene age. II. Distribution and Abundance Baiji were found mainly in the mainstream of the middle and lower reaches of the Yangtze River ( Zhou et al., 1977) ( Fig. 2 ).
    Out of the seven times Mark and Douglas had visited China, never did they encounter a wild and free Yangtze river dolphin. It is even more impossible now with the likelihood that Lipotes vexillfer may be the first cetacean to have been driven to extinction by human activity.
