The New York Times reported on a Giant Tortoise who helped save his species due to his high sex drive. While other males were refusing to mate in captivity this wasn’t an issue for one who was named Diego
Diego has fathered hundreds of progeny — 350 by conservative counts, some 800 by more imaginative estimates. Whatever the figure, it is welcome news for his species, Chelonoidis hoodensis, which was stumbling toward extinction in the 1970s. Barely more than a dozen of his kin were left then, most of them female.
