Aldabra giant tortoise



The Aldabragiant tortoise(Aldabrachelys gigantea), from the islands of the Aldabra Atoll in theSeychelles, is one of the largest tortoisesin the world.Historically, giant tortoises were on many of the western Indian Ocean islands, as well as Madagascar, and the fossil record indicates giant tortoises once occurred on every continent and many islands with the exception of Australia and Antarctica. Many of the Indian Ocean species were thought to be driven to extinction by over-exploitation by European sailors, and they were all seemingly extinct by 1840 with the exception of the Aldabran giant tortoise on the island atoll of Aldabra. Although some remnant individuals of A. g. hololissa and A. g. arnoldi may remain in captivity, in recent times, these have all been reduced as subspecies of A. g. gigantea.
