One of the world’s oldest living animals, Harriet the tortoise, reached the grand old age of 175 on November 15. Harriet has spent the past 17 years at Australia Zoo near Brisbane, but her keepers say the Giant Galapagos Land Tortoise had a famous previous owner. They reckon scientist Charles Darwin, who came up with the theory of evolution, collected her in 1835. Harriet is recognised by the Guinness Book of Records as the oldest living chelonian, or reptile with a shell. Harriet celebrated her day with a portion of a pink hibiscus flo-wer cake. Keepers, Richard Jackson, said she was still a sprightly as ever: “She’s showing no real signs of slowing down.”
