178-year-old tortoise believed to be world's oldest

A 178-year-old tortoise is believed to be the world's oldest living animal.

Images of the animal, named Jonathan, with a Boer war prisoner and guard in 1900 were recently sold at auction near Winchester, England for £4,000 - and it has now been discovered that the Testudinipae cytodira is still alive and living on the remote island of St Helena.
