The Chinese dolphin might not be extinct

Scientists declared the white dolphin, native to China's Yangtze river, extinct last year. But there is a shred of hope: the animal may have been spotted swimming in the wild.

Wang Ding, a researcher with the Institute of Hydrobiology under the Chinese Academy of Sciences, said a man saw and shot a video of what appears to be a baiji or white flag dolphin in central China's Anhui province on August 19.

The white flag dolphin survived for millions of years but was declared effectively extinct in December after a fruitless six-week search of its Yangtze River habitat.
