But Jonathan is much more than a record holder. He’s a beloved member of the St. Helena community, an unexpectedly lively character despite his advanced age, and now the subject of fascinating scientific research that could help researchers better understand why certain animals live exceptionally long lives. His story combines nearly two centuries of history with some remarkable discoveries about aging.
