File photo taken on Feb. 19, 2007 shows staff of China Giant Panda Protection Research Center carrying Xiang Xiang's body in Wolong, southwest China's Sichuan Province. Xiang Xiang, the world's only artificially bred panda living in the wild, was confirmed dead on May 31, 2007. Experts speculated that Xiang Xiang might have fallen from a high place after getting into a fight with the original "residents" for food or territory. Xiang Xiang was found dead on snow-covered ground on Feb. 19, some 40 days after scientists picked up the panda's trace for the last time via a wireless tracking device it wore on its neck. Officials attributed the long delay in publicizing Xiang Xiang's death to the need for a full investigation.  (Xinhua, File Photo)
