Good rare stamp.
The southern white rhinoceros or southern square-lipped rhinoceros (Ceratotherium simum simum), is one of the two subspecies of the white rhinoceros (the other being the much rarer Northern white rhinoceros). It is the most common and widespread subspecies of rhinoceros. As of late December 2007, the total population was estimated at 17,460 southern white rhino in the wild, making them by far the most abundant subspecies of rhino in the world. South Africa is the stronghold for this subspecies (93.0%), conserving 16,255 individuals in the wild in 2007. The current census from Save the Rhino's official website revealed there are 19,682–21,077 southern white rhinoceros since 2015.
