These mammals are easily recognised by their prehistoric features and the horns on their forehead. Rhinos are bold and have been seen to graze right next to Lions, with the Lions being equally un-fazed. Poachers are greatly responsible for the decreasing Rhino population. In the Kruger National Park White Rhino Ceratotherium simum occur mostly in woodlands between the Sabie and Crocodile Rivers, and less around Shingwedzi and Letaba. The Black Rhino Diceros bircornis is found around thorny thickets and dense bush in southern Kruger between Skukuza and Pretoriuskop and also south of Lower Sabie near Crocodile Bridge.
