Hangzhou residents walk past a picture of Pei Pei in the zoo August 24, 2004. They came to see Pei Pei but only learned that Pei Pei has died. 

Peipei, the eldest raised panda in the world, died at the age of 33 at a zoo in Hangzhou City, capital of eastern Zhejiang Province.

The zoo said Peipei died on August 13. Peipei's age was the equivalent of 100 in human years, and the panda's organs simply failed. Usually, a panda in the wild has an average life span of 13 years while those in captivity can usually live up to 20 years.

Peipei's body will be anatomized and studied, the zoo said.
