According to zoologists Jonathan the tortoise is one of the oldest land animals. Born in 1832 this tortoise has seen three centuries . This would make him a total of 190 years old. Some have suspected that Jonathan could be over 200 years old. The problem is that there is no record of his exact date of birth. His species has longevity, but it is not fully understood how it was attained. There must have been some form of adaptation, which enabled tortoises to live so long. Genetics might also explain this phenomenon. It could be a trait of natural selection. Jonathan's diet consists of cabbage, carrots, apples, cucumber, and various fruits. His activities consist of eating, sleeping, and mating. The reason this animal generates interest is due to Jonathan's life span. It is possible he could live for another century or more. This feat has gotten Jonathan recognition in the Guinness Book of World Records. Not only is he the oldest land animal, but remains the oldest tortoise. Jonathan's scientific name is Aldabrachelys Gigantea Hololissa. The giant Seychelles tortoise resides in St Helena.
