How many Yangtze river dolphins are left?

Answer 1

As of the latest estimates, the Yangtze river dolphin, also known as the baiji, is considered functionally extinct, with no confirmed sightings since 2002. Conservation efforts have failed to locate any remaining individuals, and the species was declared critically endangered prior to its presumed extinction. Various factors, including habitat loss, pollution, and overfishing, have contributed to its decline.
