The world’s oldest panda in captivity, known as Pan Pan, has reportedly died at the age of 31.
Pan Pan’s lineage takes up almost 25 percent of all pandas living in captivity. He’s known for his virility, surviving 130 of his descendants around the world.
According to the China Conservation and Research Center, Pan Pan died at the age of 31 on Wednesday in China’s Sichuan province, where he lived most of his life. 31 years equates to be around 100 human years.
Pan Pan was born in the wild in 1985. He was found when he was 2 months old and brought to the Sichuan facility, according to the Chinese newspaper Huaxi City Daily.
According to CNN, when he was younger, he was known for his “strength and agility.”
He was also later known for his ability to frequently reproduce. Huaxi City Daily said that during the late 1980’s and early 1990s, it was one of the only four males capable of naturally mating.
His first offspring was born in 1991, and he later fathered even more descendants, CNN said.
All those descendants totaled to about 130 pandas, which now populate zoos all over the world, according to CNN.
Reports now say that his lineage covers almost 25 percent of the world’s captive pandas. Notable descendants include Bai Yun in California’s San Diego Zoo and Hua Mei and Tai Shan, which were both born in the US and returned to China.
According to the Panda Research Center, Pan Pan had been suffering from cancer over the past year, which caused his health to deteriorate.
He had reached his worst condition around three days before his death. The oldest female panda in captivity, Jia Jia, had also passed away earlier this year in Hong Kong’s Ocean Park.
