On 4th February, staff of Nantong Maritime Safety Administration took photos of finless porpoises playing while cruising in the water area near China Merchants Industry Haimen Base and Haitai Ferry.

Yangtze River finless porpoises have lived on Earth for 25 million years. It is an ancient and rare species unique to the Yangtze River. Its mouth naturally curves up, forming a smile-like shape. It is called the ‘smiling angel’ of the Yangtze River.
