Shi Shi

In 1992, a wild Shi Shi was captured in Sichuan, China. In 1996, he underwent rehabilitation and was delivered to the San Diego Zoo to mate with Bai Yun. In 1996, China brought Shi Shi and Bai Yun to the San Diego Zoo as part of a 12-year study loan agreement. Hua Mei, the first panda in the United States to survive infancy, is the product of artificial insemination between Shi Shi and Bai Yun, despite the fact that they never actually mated.

Shi Shi's sperm was used to artificially inseminate Bai Yun in 1999, and the result was the birth of Hua Mei. He was subsequently found to be much older than first thought, and Gao Gao took his place as Bai Yun's mate. Shi Shi gained notoriety while working with Bai Yun at the San Diego Zoo.

Shi Shi was sent back early in 2003 due to his age and his refusal to mate, even though Shi Shi and Bai Yun were originally supposed to return to China in 2008. He was believed to be in his 30s when he passed away in 2008 in the Guangzhou Zoo. Shi Shi is one of the oldest pandas in the world.
