Jia Jia the panda has set a new Guinness World Record for being the oldest panda in captivity. Animal keepers at Ocean Park, in Hong Kong, celebrated Jia Jia's 37th birthday on July 28. Included in the celebration was one of the park's other resident pandas and the world's second-oldest panda, An An, who turned 29 years old. Ocean Park also has two other resident giant pandas: Ying Ying and Le Le. Check out some photos of the pandas that call Ocean Park home.
