This picture taken on November 10, 2018 shows a Yangtze finless porpoise swimming in a pool at Baiji dolphinarium in Wuhan. One of the world's few freshwater porpoise sub-species and only aquatic mammal left in China's longest river, the Yangtze finless porpoise is critically endangered due to pollution, overfishing, hydroelectric dams and shipping traffic.
