She was hatched when Queen Victoria was still a teenager she's now 175 years old - By Clare Raymond
HER skin is wrinkled and she's carrying a few extra pounds, but there's still a twinkle in the old girl's eyes.
In fact she's in uncommonly good shape for someone who was born before Victoria came to the throne.
Harriet, a giant (vegetarian) Galapagos Land tortoise and the world's oldest living creature, celebrates her 175th birthday.
Whilst animal research is not a good way to determine effects on humans it's still a good example of the potential benefits of a vegan / vegetarian diets.
Harriet dines on a diet of aubergines, courgettes, string beans, parsley, squash, endives, carrots, tomatoes, bok choi and her favourite morning treat - pink hibiscus flowers.
While Harriet is currently the oldest living being on earth, she isn't the oldest living animal ever.
According to the Guinness Book Of World Records, a Madagascar radiated tortoise called Tui Malila presented to the Tongan royal family by Captain James Cook in the late 1700s, was either 188 or 192 when it died in 1965.
