Baiji

The baiji is a rare river dolphin that once lived in China's Yangtze River. Known as the 'Goddess of the Yangtze,' it may be the first dolphin species to vanish due to human activity. No confirmed sightings have been reported in over two decades.

• Its scientific name means 'left behind flag bearer' in Latin.
• Fishermen once believed it brought protection and good luck.
• Surveys of the Yangtze have found no baiji since the early 2000s.
