Sumatran tigers are the smallest surviving tiger subspecies and are distinguished by heavy black stripes on their orange coats. They are protected by law in Indonesia, with tough provisions for jail time and steep fines. But despite increased efforts in tiger conservation—including law enforcement and antipoaching capacity—a substantial market remains in Sumatra and the rest of Asia for tiger parts and products. Sumatran tigers are losing their habitat and prey fast, and poaching shows no sign of decline. Original public domain image from Flickr
