The white rhinoceros (Latin: Ceratotherium simum) is the largest representative of the rhinoceros family. Despite the name, the color of the white rhinoceros differs slightly from the color of the black one, and this name, apparently, came from the distortion of the Boer word wijde (means: wide, broad-snouted), which the English changed in sound to "white". From the English, the name passed into other languages.
The main difference between the white rhinoceros and the black one is the wide flat upper lip (the black one has a pointed lip in the form of a proboscis). This structure is quite consistent with its purpose: the main food of the white rhinoceros is not bushes, but grassy vegetation. When grazing, the animal bites off grass at the very ground, and the sharp keratinized edge of the lower lip compensates for the missing incisors.
