![]() ![]() Some 20,000 giant tortoises of other subspecies still live on the Galapagos. The differences in appearance between tortoises from different Galapagos islands were among the features which helped the British naturalist Charles Darwin formulate his theory of evolution. The species habitat, forested hill streams of southern China, is also at risk with the threat of degradation in the area. Their habitat furthermore suffered when goats were introduced from the mainland. 2 The Pinta Giant-Tortoise went extinct because of harvesting by whalers and other mariners. 2 Despite extensive surveys, no other tortoises have been found on Pinta Island nor in any of the world’s zoos. Tortoises were plentiful on the Galapagos islands until the late 19th century, but were later hunted for their meat by sailors and fishermen to the point of extinction. 2 Chelonoidis abingdonii is listed in this category because the last known individual of the species, known as Lonesome George, in captivity since 1972, died in 2012. They said his body would probably be embalmed to conserve him for future generations. Galapagos National Park officials said that with George's death, the Pinta tortoise subspecies has become extinct. He became a symbol of the Galapagos Islands, which attract some 180,000 visitors a year. He also shared his corral with female tortoises from Espanola island, which are genetically closer to him than those from Wolf volcano, but Lonesome George failed to mate with them. Lonesome George became part of the Galapagos National Park breeding programme.Īfter 15 years of living with a female tortoise from the nearby Wolf volcano, Lonesome George did mate, but the eggs were infertile. Lonesome George was first seen by a Hungarian scientist on the Galapagos island of Pinta in 1972.Įnvironmentalists had believed his subspecies (Chelonoidis nigra abingdoni) had become extinct. While his exact age was not known, Lonesome George was estimated to be about 100, which made him a young adult as the subspecies can live up to an age of 200. ![]() Watch: What happened when Darwin arrived on the Galapagos Islands in 1835?.Kleinmann's tortoise, also known as the Egyptian tortoise, is the smallest of the Mediterranean species.They get their name from the striking yellow and dark brown star pattern on their shells. ![]()
