The Galápagos Islands giant tortoise died in 2012 at more than 100 years old, thus marking the end of a subspecies, the Pinta Island tortoise (Chelonoidis nigra abingdoni). Since he was discovered in 1972, the 5-foot-long, 200-pound reptile became a symbol of Galápagos conservation efforts. He never married, hence the name “Lonesome George.”
