Ungulate, << UHNG gyuh liht or UHNG gyuh layt, >> is any mammal whose toes end in hoofs. The name comes from the Latin word ungula, meaning hoof. It is a traditional grouping rather than a scientific classification. Ungulates may be divided into odd-toed ungulates and even-toed ungulates. Odd-toed ungulates include horses, which have one toe on each foot, and rhinoceroses, with three. Even-toed ungulates include deer, with two toes per foot, and pigs, with four. Ungulates are the only horned mammals, but not all ungulates have horns. All ungulates are herbivores (animals that eat chiefly plants). Elephants, the largest land animals, are ungulates.
