White Rhino – Ceratotherium simum There are several theories to explain the origin of the name ‘white .from the Afrikaans ‘wyd’ or Dutch ‘wijd’ (meaning wide) not a color, as they are not white at all. There are the folds of skin near the top of the forelimbs, and in the flank where the upper part of each hindlimb joins the body. The skin color is gray but is modified by the earth color used for the sketches.
