"A mural painted on a suburban wall in Johannesburg, South Africa calls for the halt to rhino poaching, Friday, Dec. 18, 2013 in a bid to save the species from extinction due to killings for the rhinos horn. Veterinarians are racing to learn more about rhino anatomy so they can swiftly treat survivors of attacks by poachers whose arsenal has included assault rifles, high-caliber weapons that can fell a rhino with a single shot and drug-tipped darts that knock it out. The big five game animals referred to in the mural as the ""big four"" in the future, are lion, African elephant, Cape buffalo, leopard, and rhino.  (AP Photo/Denis Farrell)"
