Harriet has been a favourite of mine for a while,not as old as the Indian jobby but still been around a long time.

Age: 176 year/s
Sex: Female
Collected by Sir Charles Darwin in 1835, Harriet is the oldest living animal on the planet. She gives biologists an insight into the potential longevity of giant tortoise species and to the damage potentially already done in skewing the age structure of existing populations. She is the oldest captive land animal on the planet at present. It is a privilege and an honour to meet this beautiful animal, and thousands of people all over the world will attest to this. Harriet also enjoys eating hibiscus flowers and a good scratch!

PS Australians have a tendancy to exaggerate a bit.
