White & Black Rhino

I've purposely separated the images I took of White and Black Rhino so as not to give the location away. Both species are endangered; the Black Rhino is critically endangered, thanks to poaching for their horns. Poaching is predominantly to meet the demand of Asian markets in China and Vietnam for traditional medicine, believed to cure anything from asthma to cancer. This couldn't be further from the truth however, as their horns are made of keratin (the same stuff as our hair).
