Range Description

The Yangtze Finless Porpoise is endemic to the middle-lower Yangtze River drainage basin in eastern China, from Yichang downstream to the estuary near Shanghai. It is now almost completely restricted to the main river channel and its two largest appended lakes (Poyang and Dongting). It formerly also occurred, at least occasionally, in some large adjacent tributaries, but has now been extirpated from most of them (Zhang et al. 1993, Yang et al. 2000, Xiao and Zhang 2002). Of the seven extant species of porpoise (Phocoenidae), this is the only population found in freshwater (Gao and Zhou 1995). Figure 1 (in Supplementary Material) shows the distribution of Yangtze Finless Porpoise.
