Lessons from the Baiji Dolphin Extinction

The Yangtze River dolphin or baiji was declared functionally extinct in 2006, offering critical welfare lessons for other endangered river cetaceans.

Key Facts

Welfare Considerations

Prior to extinction, baiji individuals faced prolonged suffering from gillnet entanglement, propeller injuries, and electrofishing. The last individuals likely died in isolation with no conspecifics. The finless porpoise now faces identical threats with the same trajectory. The welfare lesson from baiji is that waiting for populations to become critically small before acting guarantees that remaining individuals face greater per-capita suffering with each death.
