Adwaita was a male giant tortoise, who lived at the Alipore Zoological Gardens in Kolkata, India. Born in 1750, he was a gift given to a British officer, who then gifted the Giant Tortoise to a series of zoos in perpetuity.

In 2006, his shell was found cracked, which led an infected wound underneath. He eventually succumbed to liver failure and passed away. He was the oldest living terrestrial mammal and tortoise.
