description Baiji Overview
The baiji was a critically endangered Chinese river dolphin, belonging to the Lipotyde family. It was one of only two known species of freshwater dolphins and uniquely adapted to the Yangtze River’s complex ecosystem. Its distinct appearance – characterized by a rounded head and pale grey coloration – made it a flagship species for conservation efforts in China. Sadly, the baiji is now functionally extinct, representing a significant loss of biodiversity and highlighting threats to freshwater habitats worldwide.
Scientists and researchers studying river dolphin evolution and freshwater ecology rely on its limited historical data.
help Baiji FAQ
Is the Yangtze River dolphin (Baiji) extinct?
The baiji, or Chinese river dolphin, is functionally extinct following a comprehensive 2006 scientific survey that failed to find a single individual in the Yangtze River. While there have been unverified, sporadic sightings since then, it is widely considered the first dolphin species driven to extinction by human activity.
What caused the extinction of the Baiji?
The baiji was pushed to extinction by severe habitat degradation in the Yangtze River, primarily caused by heavy boat traffic, pollution, and overfishing. The dolphins frequently drowned after becoming entangled in illegal fishing gear like rolling hooks and electrofishing equipment.
How was the Baiji adapted to living in a river?
Because the murky waters of the Yangtze River offered practically zero visibility, the baiji was nearly blind and relied entirely on echolocation to find its prey. It had a long, highly sensitive beak that it used to probe the muddy river bottom for small fish.
When was the last confirmed sighting of a wild Baiji?
The last widely accepted and confirmed sighting of a wild baiji occurred in 2002, and a captive individual named Qiqi died in the Wuhan Institute of Hydrobiology that same year. The 2006 international expedition officially concluded the species was functionally lost.
