Lifespan

Scientists are not sure how long giant pandas live in the wild, but they are sure it is shorter than lifespans in zoos. They estimate that lifespan is about 15-20 years for wild pandas and about 30 years for those in human care. Chinese scientists have reported zoo pandas as old as 35. The Smithsonian National Zoo's Hsing-Hsing died at age 28 in 1999.
