A pod of harbor seals rest on a flat rock in a reserve in northeast China’s Liaoning province, May 3, 2013. Harbor seal is nationally protected species and its number has declined to less than 2,000 from 8,000 in the 1930s, a result of the warmer climate, poaching and marine pollution. The coastal provinces like Shandong and Liaoning have taken actions to recover harbor seal’s population by setting up reserves and enhancing law enforcement. (Xinhua/Yang Qing)
