White Rhinoceros

Now you know that white rhinoceros is an African species. You may infer from the name that the animal could be white in color. But, in fact, the color of this rhinoceros species is much like black rhinoceros - brownish gray. You may find many different explanations for the name of this rhinoceros species.
According to some, the name is associated with the light-colored horn of the animal. It is also suggested that the skin of this rhinoceros appears to have a lighter shade, as it is often found to be covered with chalky soil.
One of the popular contentions is that the name white rhinoceros may have been derived from the Dutch word 'wijd', which means wide and not white. As per this theory, the Dutch word has been used to describe the wide mouth of these animals. These animals are also referred to as square-lipped rhinoceros.
Scientifically termed as Ceratotherium simum, white rhinoceros has two sub species and they are northern white rhinoceros (Ceratotherium simum cottoni) and southern white rhinoceros (Ceratotherium simum simum). While there is no considerable decline in the population of southern white rhinoceros, northern white rhinoceros is in the critically endangered list of the IUCN.
As per estimates, there are only eight of them left in the world, that too in the zoos. As of now, these animals are considered extinct in the wild. Both these sub species are found to have the same body color. However, they differ in their lip shape and habit of eating.
Northern white rhinoceros have wide, square lips, whereas the southern variety has a pointed upper lip. The lip shape is associated with their eating habits. While, the northern type are grazers that feed on the grass from meadows, the southern version are browsers that feed on shoots and buds.
