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 box turtle is the only species that spends most of its life on land and hibernates in the soil; the rest hibernate underwater. Many turtles have very long lifespans! Box turtles can live well over 100 years and other turtles like the spotted turtle can live over 50 years. Because turtles live so long, it is not so important that they produce many offspring every year. In fact, most turtle eggs or the hatchlings are eaten by birds, foxes, or other predators.
