The white rhinoceros ((Ceratotherium simum) name comes from the Afrikaan’s word “weit” which means wide and refers to the animal’s wide mouth used for grazing. early English-speaking settlers in South Africa misinterpreted the "weit" for "white" and the rhino with the wide mouth ended up being called the white rhino and the other one, with the narrow pointed mouth, was called the black rhinoceros. Also known as the white rhino or square-lipped rhinoceros, the white rhinoceros is the second-largest land mammal and the largest extant species of rhinoceros. The majority of white rhinos are found in South Africa, with smaller populations in Namibia, Zimbabwe, and Kenya.
