YUEYANG, China, April 18 (UPI) -- Chinese wildlife officials say the corpses of 12 endangered finless porpoises, including a pregnant one, have been found around Dongting Lake in Hunan province.
The discoveries have raised concerns finless porpoises, which have lived in the Yangtze River and adjacent lakes for more than 20 million years, could become extinct within 15 years, scientists said.
