Baiji (Lipotes vexillifer)
The Baiji is not extinct yet. Early in January of this year, the rare river dolphin was proclaimed extinct. After an extensive and fruitless search of the polluted Yangtze River in China, the dolphin's sole habitat, scientists gave up hope. Now, a digital video has provided evidence that at least one Baiji may survive in a small section of river. Although efforts may be made to capture and transport any remaining dolphins, scientists warn that extinction is still almost the guaranteed outcome--even if a few dolphins still survive, with such low numbers, a comeback is highly unlikely.
