Puerto Ayora, Ecuador—He’s over 100 years old, but his sex life is the stuff of legend. Diego the Tortoise is his species’ version of the ladies’ man, and his exploits have helped save his kind from extinction. Diego, a Galapagos giant tortoise, has fathered an estimated 800 offspring, almost single-handedly rebuilding the species’ population on their native island, Española, the southernmost in the Galapagos Archipelago.
