Belgrade zoo marks 83 years with Muja, world's oldest captive alligator

Muja has lived through multiple bombing campaigns and several countries -- all while never leaving a tiny pool in Belgrade's zoo for 83 years, making him the world's oldest captive alligator. While zookeepers don't know his exact hatch day, the reptile arrived in Belgrade this week in August of 1937 from a German zoo. He officially became the world's oldest captive alligator when Moscow zoo's famous Saturn, born in 1936, died in May.
