Before his arrival there were just two male and 12 female members of the Chelonoidis hoodensis species alive on Espanola, and they were too spread out to reproduce. He, however, has done more than any other tortoise to turn that around and now lives at a tortoise breeding centre on Santa Cruz Island, where he shares an enclosure with six females Legend.
