High Quality Content by WIKIPEDIA articles! Harriet was a Galápagos tortoise (Geochelone nigra porteri) who had an estimated age of 175 years at the time of her death in Australia. Harriet is the second oldest tortoise ever authenticated, the oldest being Tu'i Malila, who died in 1965 at the age of 188. She was reportedly collected by Charles Darwin during his 1835 visit to the Galápagos Islands as part of his round-the-world survey expedition, transported to England, and then brought to her final home, Australia, by a retiring captain of the Beagle. However, some doubt was cast on this story by the fact that Darwin had never visited the island that Harriet originally came from.
