He said: Jonathan is the sole survivor of three tortoises that arrived on St Helena Island in 1882. He was already mature when he arrived and was at least 50-years-old. Therefore his minimum age is 176-years-old. He is the oldest inhabitant on St Helena and is claimed to be the oldest living tortoise in the world. He lives in the grounds of Plantation House which is the governor's residence with five other tortoises who are much younger than him.
The actual documentation of the age of any species of sea turtle is difficult. What we do know is that sea turtles live a long time (some can live up to 50 years or more) and have similar lifespans to humans.. Most marine turtles take decades to matureâbetween 20 and 30 yearsâand remain reproductively active for another 10 years.
