Visitors watch Harriet the Galapagos Land Tortoise in her enclosure at the Australia Zoo in northern Australia before she celebrated her 175th birthday November 15, 2005. One of the world's oldest living animals, Harriet celebrated her 175th birthday on Tuesday -- with a pink hibiscus flower cake at her retirement home in northern Australia. Australia Zoo, where Harriet has spent the past 17 years, says the Giant Galapagos Land Tortoise was collected by British scientist Charles Darwin in 1835, although some historians have disputed this.
