There were around 11,000 white rhino counted in South Africa in 2005, but for unknown reasons the white rhino rate of reproduction is low. The white rhino is the only species of rhino that is not critically endangered.
The color of the white rhino ranges from yellowish brown to gray and not white as the white rhinos name suggests (the white rhinos name is thought to have originated from a mis-translation of the white rhinos names from Dutch into English, with the white rhino thought to have been originally named the wide rhino and not the white rhino).
The ears of a white rhino can move independently which helps the white rhino to pick up more sensitive sounds but the white rhino depends most of all on its sense of smell. The white rhino, like other species of rhino has extremely poor eyesight for such a large animal.
