Shuan Shuan, the oldest panda in Mexico, has died at the age of 35.

Mexico City’s Environment Department said the panda died at the Chapultepec Zoo in the capital. The department did not list a cause of death.

But it said Shuan Shuan lived well beyond her species’ life expectancy in the wild, which it put at 15 years.
