A quick word about that name, “white rhino.” There are five existing species of rhinoceros: greater one-horned (sometimes called “Indian”), Javan, Sumatran, African white, and African black. The white rhino is, of course, not “white” at all, as can easily be seen in this photo of Tom. The most popular theory of the etymology of this name is that it is derived from the Afrikaans word weit, which means “wide,” referring to this species’ broad muzzle.
