The world's oldest panda in captivity, Jia Jia, just celebrated her 38th birthday - the equivalent of 114 years old in human terms - at Hong Kong Ocean Park this month.

The female panda holds two Guinness World Records: the oldest panda ever in captivity and the oldest panda living in captivity.

The average life span for wild pandas is 14 to 20 years, and 25 to 30 years for those in captivity.
