An old wives' tale says that you can tell the age of a tortoise by counting the rings on its shell. It is not true. The growth of a tortoise depends upon its access to food and water. A desert tortoise may have to go days without eating, while a gopher tortoise may have plenty of access to food.
In China, the tortoise is the symbol of longevity. There is a good reason for this. A tortoise can live a long time. Some of these aged tortoises have even made the record books for longevity.
Tu'i Malila was a radiated tortoise from Madagascar. This tortoise was said to have been the longest-living tortoise on record. It was born around 1777.
