Summary

The world's only freshwater porpoise, the Yangtze finless porpoise, is down to fewer than 1800 individuals, less than half the estimated population a decade ago. A few dozen porpoises live under the watchful gaze of rangers in Tian-E-Zhou Oxbow Nature Reserve, an oxbow lake that once was a 21-kilometer-long section of the Yangtze River. But time is running out: Unless threats to its survival are met head on, the porpoise could be gone in 15 years, ecologists say.
