There are two species of rhino that can be seen on African safaris, the black rhino and the white rhino. These names are misleading as they are not truly distinguished by their color. The black rhino is more accurately the hook-lipped rhino as it has a prehensile upper lip used to browse vegetation from shrubs, while the white rhino is the square-lipped rhino with a squared off mouth made to graze the grasses. Both rhino are extremely rare and continue to be vulnerable to poaching because of the high demand for their horns in some Asian countries. In some areas rhino have human attendant guards making them easy to find but not much of a wild feeling. Many safari areas completely lack rhino so if a rhino sighting is paramount be sure to include an appropriate area on your safari.
Ngorongoro Crater is a good location to sight black rhino. White Rhino are not found in Tanzania.
