Steve, a tiny dibbler at Perth Zoo, reportedly helped save his endangered species without ever becoming a father. Female dibblers prefer larger mates, and Steve was too small and apparently didn't smell appealing. Keepers used him as the first male females encountered during breeding trials. After meeting Steve, females found the next males more attractive and were more willing to mate. According to the zoo, Steve lived a long life as an unlikely conservation hero.
