American_alligator_Muja_-_oldest_in_the_world_

How old is Muja ?

Zoo site:

It arrived in Belgrade Zoo one year after its creation, 12 September 1937 as an adult animal, with another alligator, in large contingent of animals from a German zoo.
Today, he is the only remaining inhabitant of the Zoo who managed to survive the Second World War...

He's in very good condition. No odd teeth, claws and whole habitus are pretty good.
