and we tern now to an animal hunt that has many outraged tonight. We're talking about the black rhino, and the price one hunter paid at a texas auction to travel overseas to kill one of these endangerered animals. Here's abc's muhammad lila now. Reporter: It's literally a license to kill. Why? Why do this senseless killing? Reporter: Overnight, the dallas safari club auctioned off the chance to kill a real life black rhino in africa. The winning bid? 350,000. The winner's name kept anonymous. The auction drawing these protest, even an online petition with 60,000 signatures and growing. It's sad. Especially an endangered species. Reporter: Among those here -- mine says "honk to save the rhinos." Reporter: The reis siblings, child activists crusading to save the endangered species. Maybe they're just doing that so they can get a few pictures with the rhino laying down dead. Reporter: There are only around 4,000 to 5,000 black rhinos left in the wild. And when we reached out to the dallas safari club for a statement, they sent us this. Saying, "science shows that selective hunting helps rhino populations grow." And, that the rhino targeted will be hold, aggressive, and "known to charge and kill younger, breeding class bulls, cows and even calves." Executive director ben carter stating, "i'm proud of our organization for taking a stand to help ensure the future of an iconic species." All of the money will go towards rhino conservation. In other words, killing one to save many others. An argument that, for many, just doesn't fly. Muhammad lila, abc news, new york.
