Baiji Dolphins

April 23, 2022

Baiji dolphins are freshwater river dolphins currently found in the Yangtze River in China only. They are also referred to as whitefin, Yangtze River, or Chinese river dolphins. The Baiji is also casually referred to as the Goddess of the Yangtze. Sadly, this river dolphin was declared extinct in 2007 after a failed six-week mission in search of one.
