Shi Shi
Gao Gao arrived at the San Diego Zoo in January 2003 and replaced Shi Shi as Bai Yun's mate. This has proven to be a very successful pairing — Gao Gao and Bai Yun are the parents of Mei Sheng (M), Su Lin (F), Zhen Zhen (F), Yun Zi (M), and Xiao Liwu (M), all conceived via natural mating. He has three grandchildren, among them a male born to Su Lin on July 7, 2011.
