Moscow Zoo
No average lifespan for an alligator has been measured. One of the oldest recorded alligator lives was that of Saturn, an American alligator who was born in 1936 in Mississippi and spent nearly a decade in Germany before spending the majority of its life at the Moscow Zoo, where it died at the age of 83 or 84 on 22 May 2020. Another one of the oldest lives on record is that of Muja, an American alligator who was brought as an adult specimen to the Belgrade Zoo in Serbia from Germany in 1937. Although no valid records exist about its date of birth, it is now in its 80s and possibly the oldest alligator living in captivity.
