"DIED. ADDWAITYA, around 250 years old, giant tortoise thought to have been the world's oldest living creature; in a zoo in Calcutta. Brought from the Seychelles to India by British sailors in the 1700s, Addwaitya (Bengali for "the one and only") first belonged to Robert Clive, who helped establish colonial rule in India. Clive died in 1774, but his pet stayed on in the garden of his estate, moving to the zoo 100 years later."
