WUHAN, XINHUA - A school of 29 black finless porpoises have given birth to 11 baby porpoises since leaving their former home in the main course of the Yangtze River and settling in a new home last year.
The rare mammals now live in the Tian'ezhou White-Flag Dolphin National Nature Reserve in central China's Hubei Province, free from the polluted water of the main course, and the dangers of motorboats and fishing equipment.
The success story of the black finless porpoises offers scientific proof that the white-flag dolphin, a rare mammal on the verge of extinction in the Yangtze River, can be relocated for protection, scientists said.
