    Finless porpoises, like white-flag dolphins (or baiji), are rare mammals endemic to the mainstream of the Yangtze River, China´s longest, and its numerous lakes. They are known among locals as "jiangzhu" (literally "river pig"). In 2006, it was found that there were only 1000-1200 finless porpoises in the Yangtze River. Finless porpoises are totally different from fish. They are viviparous mammals. Yangtze finless porpoises have a reproduction mode like that of humans. So their reproductive rate is very low. Protecting and breeding finless porpoises is a matter of great urgency. Today we will tell you a story about finless porpoises Tao Tao in Wuhan, Hubei.
