Ungulate, any hoofed mammal. The ungulates constitute a large group of dissimilar animals whose last toe joints are encased in hooves. The group is divided into four orders. The odd-toed ungulates include the horse, ass, rhinoceros, and tapir. Even-toed ungulates include the pig and ruminants such as the hippopotamus, camel, giraffe, antelope, deer, cattle, sheep, and goats. The other orders comprise the elephant and the rabbit-like hyrax, the two extremes in size among the hoofed animals. Most ungulates are herbivorous. Ungulate species are native to all continents except Australia.

Scientific classification: Odd-toed ungulates belong to the order Perissodactyla. Even-toed ungulates are in the order Artiodactyla. Elephants are in the order Proboscidea. Hyraxes are in the order Hyracoidea.
